That custom 7800 case though.  👌

I've been told this is likely just an issue for ABS plastics that of course all of our stuff was made back then. Apparently PLA used with 3D printing isn't affected as much? But I don't have the means to test that myself. But yeah... kinda disappointed too since I had really thought this was the fix I'd been looking for to keep the AV jacks I install nice and tight, but ehh. It isn't.
 
 

7800 got Xenophobe? Holy cow! And, yes, Food Fight of course.  I forgot to put that one on my list.  I especially love the replays when they happen. I've been playing Donkey Kong a lot since I recently scored a 7800 copy.  I'm not a huge DK fan but something about the 7800 version is just pleasing to play.  Who knows.  I don't understand it either.
Choplifter I played on the SMS first.  I never knew of the game on any Atari until maybe 10 years ago.  So when I popped the 7800 version in for the first time I was shocked how much stuff was "missing" before I learned Sega added all those extras.  I like the 7800 version better but it's tough.

Choplifter also exists on the 5200 and 8-bit line. But is uses artifacting so you really need to play if via RF or composite output to see any colors from it.
And yeah, Xenophobe is on the 7800. I think it plays better than the NES version and looks more colorful, but you only have one character to play as and it does get quite repetitive. Rampage on the 7800 is also a lot of fun and I played it a ton back in the day. But it is the definition of repetitive and so I find myself tiring of it quickly these days when I try and play it now.
 

Ah.  I was wondering. With DC looking like Gauntlet that's where I thought the game originated from.  I'll have to research Dandy.

That is a nice list of games for the system.  Dark Chambers was not a clone of Gauntlet, though.  It was based on a computer game (Dandy) that was the inspiration for Gauntlet. 

The 7800 is my favorite Atari console but my list of games would be a bit different as I found myself more interested in the games that weren't repeats from the previous generations at the time. 
F-18: Hornet - This is not one that I play that often these days, but when I first had the system I played it all the time and once I learned exactly how the game works, similar to 2600 Adventure, I would find ways to do stuff you weren't supposed to do like flying in the other direction and stuff like that. But at the time I was pretty impressed with everything you could do in the game with the different missions.
Crossbow - shouldn't be a surprise for anyone this is on my list heh. But I've always enjoyed this game on the 7800 and prefer to play it with a controller vs light gun as it is easier to setup your cursor on the screen in known locations and just move left/right as needed to take out a good chunk of the enemies on each scene that plays out. I also thought the graphics for this game were pretty stellar back then on the 7800.
Food Fight - I had never heard or nor seen the actual arcade cabinet back in the day, but the game looked like fun when I read the box and I'm very glad I decided to pick it up back then. I play this one still from time to time as it is just so well done on the 7800.
Double Dragon - I know...kinda surprising but to me I thought this version was closer to the arcade than the NES in respect to the level designs etc. I did play the NES version as well, but always liked the 7800 version more and got to be really good at it back in the day.
Xenophobe - This is one of the games I wanted the 7800 for as the arcade cabinet was so unique in the day and I had a lot of fun playing it so when I saw it was coming for the 7800, it was pretty much the game release that made the 7800 a console I wanted in the late 80s. The irony to this is that I ended up never owning Xenophobe until much...MUCH later in life. But aside from the arcade and Lynx versions, the 7800 version is my favorite home console port of the game by far.
Galaga - was also one I picked up originally back in the day and like @Atari 5200 Guy I thought it was pretty awesome back then. Yes the NES version looks closer to the arcade but something about the 7800 version to me was just more fun to play for some reason? 
Choplifter - Is another arcade game that I had only seen in the arcade a few times and I didn't know of the releases on the 5200 and 8-bit consoles back then. So it was new to me and I played it all the time until I had method down for getting a perfect game. I still like to pop it in once in a while to see how many POWs I can save. This is another decent looking game on the 7800 as well even thought the SMS version just trounces it. (Again, I didn't know about the SMS release of the game either back then).
Joust - This was one of the few games that I already had on my 2600 and played all the time. But when I saw how much closer to the arcade look and feel the 7800 version was, I was totally on board with this one. It was also one of my mothers favorites, but oddly she still seemed to prefer to play the 2600 version more back then?
And that is my short faves list of the original released games I owned back then minus Xenophobe as mentioned before. With the home brew scene what it is on the 7800, there is just some amazing talent that has really shown just what the 7800 was able to do and with the proper resources being given, it could have done even back in the day.
 

The HOKEY in my concerto was sounding pretty bad in most stuff as well. Until his new .96 update. Once I updated to that, then Bently's Quest now sounds much closer to what it should. Although final roms of many of the recent homebrews still produce the wrong audio or no audio at all on my concerto setup. I'm not even using my concerto as I've been using the Backbit adapter in the lab and stick with my DragonFly for everything else for the time being.
 

NP and I'm glad I'm in a position to do so. I own more flash carts for the 7800 now than any other system I own in the collection as most of then only need one or two to do what I want. But as I service and work on so many 7800s (More than any other console by far), I feel I kinda need to have everything on hand so I can test as many configurations and options as I can for myself and my clients who might have the same hardware.
What I might have to do, is remove the Kiloparsec BIOS from my test 7800 and revert it back to stock BIOS. And then with Bob's permission, send Evie the Kiloparsec BIOS I've been using for her to install and test further.
Because I see the same behavior in both the Kiloparsec BIOS and the NTSC modified ones that have built in Asteroids... I will guess they both are similar designed and the reasons for the BBpro 7800 adapter not working as expected is for the same reasons in each BIOS type.
 

Evie released v1.91 yesterday for the BBPro and it has fixed a ton of stuff in the process and continues to impress me with her quick and continued support of her products.
 
As of version 1.91 all original released games are now confirmed working with my setup with a few small exceptions that I will mention below:
- Fatal Run still seems to auto start within a sec or two of the title screen coming up. Difference now is that it doesn't lock up the console and you can at least play the game. It also seems to auto skip the cutscene between levels that shows folks living and enjoying life, or turning into gravestones. But the shop works properly and it doesn't have any graphical glitches and is playable now.
- Summer Games is playable but has flickery white lines on the screen only during the opening ceremonies still but actual game events look correct and the game is completely playable.
- Tower Toppler now loads up and works! But similar to many homebrews and both Summer/Winter Games, it has little flickery white horizontal thin lines scattered about the screen throughout the game.
- Winter Games like Summer Games has the same white flickery lines that appear during the opening ceremony. But again, actual game events look correct and the game is fully playable.
 
And that is really it! If you don't see a game listed, then assume that game is now playing and working as it should. So again all of the original released games are now fully playable with just a few showing some odd graphical anomalies during their game play as noted above. 
Some other issues that appear to possible be unique to my test 7800s here, is that the Reset wire I mentioned is supposed to NO LONGER be needed. This is awesome news for everyone, but it seems that 7800s with custom BIOS in them like mine will still require this added reset wire for the time being. Not sure what the differences are but both the Kiloparsec BIOS that still isn't available publicly and the much more common Asteroids built in BIOS sold by Best and The Brewing Academy are the same and require the reset wire.
Atari 2600 games are also working again but similar to above, the custom BIOS seems to interfere with how this is supposed to work and so I have to work around the issue in my case on these test 7800s. In a nutshell the reset wire in my 7800s here is required, but also causes the 7800 to only reset into 7800 mode. As a result the 2600 game roms won't load up normally. However, if I disconnect the reset wire from the cartridge just before selecting a 2600 game, then the 2600 game will load up immediately and play without issue.
So there is a way I can at least get them to load up, but it is a PITA as it currently is for me and my 7800s here. In addition, after I've played said 2600 game and want to switch to something else, I have to reconnect the reset wire again in order to start up the BBpro adapter. I've made Evie aware of these issues but as she doesn't seem to have access to any 7800s with custom BIOS installed, it makes it difficult to figure out the problems.
This weekend, if I have time, I do plan to try and revert the Kiloparsec BIOS in my lab 7800 back to the stock BIOS setup and see if it behaves in the proper manner. My guess is that it will and would mean that for any with modified BIOS in their 7800, they might be better off to steer clear of the BBpro 7800 adapter until those issues are figured out and corrected. Which is sad because aside from this, the BBpro 7800 adapter is shaping up to be an excellent option for those looking for an easy to use flash cart for their 7800 and possibly other systems that the BBpro can support.
 

Honesty is a virtue.  Thank you for sharing.  It's true we all make goofs like this.  It's just a matter of time. 

Oh I was advised by a few others in the modding scene to just replace it and keep it to myself. But I don't see any value in hiding such a mistake. And in this case, it was easily avoided but also something very easy for anyone to do. 
But sure, I could have just replaced out the board and let it go and none including the client would have been any wiser. But that isn't how I do things. I take it for what it was, a mistake and valuable lesson to be learned from the mistake I made in this case. And yes I let the owner of this console know what happened.
 

Agreed.  However, DOSBox does an amazing job of sorting this all out.  It works great.  On a machine like this, there is no option to use expansion cards, so DOSBox is a savior. 

I think it could do 2GB DDR memory (2 * 1GB sticks), but I don't have those).

The integrated graphics in this machine is an NVidia Geforce 4 MX 440 and it runs Quake and Quake 2 pretty well!
 

I LOVED this game. I had an Esprit back in the day, partially due to this game and partially due to the Esprit being the "sister car" to the DeLorean DMC-12, as the DeLorean was based on the Esprit and engineered by Lotus at Hethel. They're sisters but not quite twins. Park them side by side and you'll see the similarities, same low, swept-back stance, both designed by Giugiaro, the DeLorean is wider, Esprit typically had a smaller engine at that time, nestled in the middle of the car rather than the rear.
Lotus Esprit Turbo Challenge was a cool game, fun to play, and one of the first racing games I can think of that was both 1.) officially licensed and branded with a car brand (Lotus) as opposed to games like Out Run which were not officially licensed through Ferrari and never used the Ferrari brand, and 2.) challenged the player with more detailed and somewhat more realistic driving physics, instrumentation, cockpit layout and gear shift. I remember playing this game and thinking it was like a flight simulator for driving. Really a neat game.

Fun Fact: The 1989 Lotus Esprit SE was the "movie car" that Richard Gere famously drove throughout the film Pretty Woman. Neither Ferrari nor Porsche wanted to be associated with Pretty Woman because one of the leads was a prostitute, so they prohibited the film from using their cars. 
Lotus didn’t mind.
 

If I remember correctly, once integrated sound chips became a standard, most DOS games took the hit.  My little Compaq has an ESS sound chip in it with legacy support.  No DOS game can find the settings and setting them manually does nothing.  
 
Words of advice...if you can opt for it, and are trying to repurpose an old computer, get a true Sound Blaster.  You'll have less headaches 😉.
 
 

Nice.  And Doom to boot!  Quake was a power hungry game when it came out.  I remember the AMD K6-2 500mhz CPU I had at the time struggled a bit.  Quake and Hexen...but I could play Final Fantasy 7 without problems.  Once I installed a Diamond Monster video card it could play anything seemed like.
Very nice all-in-one setup for sure.  Can you add more RAM if you need it or is it maxed already?

I have something very special coming in this same vein.  More info to come....

Hey that's super cool @RickR! I've been thinking of doing a similar thing but with an ancient computer. I like what you did here!  🔥   🔥   🔥   🔥 

Won't lie, I had to google that name to understand. I've never read Agatha Christie so I wasn't getting the reference at first.
And I'm just following the footsteps of the actual greats... those who actually engineered and designed these wondrous machines from our youth that helped fuel our imaginations in a way that only this new medium at the time could.

Okay, as I stated. Here is what it all looks like complete now.
 
 
Here is the wiring that has been done on the original AV jacks. I still need to wipe out the interior a bit to try and clean it a bit more but you get the idea on at least how the wiring on it is now. This is the overall wiring inside.

And here is a close up of the AV jacks with the new wiring in place. Hopefully this looks more cleaned up compared to before?

And I did manage to get pics of another console done in the same manner so you can see what I initially start off dealing with.

Once the wiring was removed off the TIA and the TIA itself was removed from the main board, this is what I'm left looking at.

I was able to straighten the legs back into shape but one of the legs is broken off a bit and shorter than the others. This is pin 12 which is part of the TIA audio but enough remains to allow it to still work.

But at least for now, this 2600 is alive and well again and ready for many more years of active gaming!
 

Well, it is looking much better now and has much better video output to boot!

So is the owner. I'm surprised that the initial mod work that had been done, didn't cause more issues. But even in that pic I posted showing the old mod board in place, you can see that something doesn't look quite right with the cartridge slot on the far left side there. I just didn't notice it until I was pouring over the thing trying to diagnose what the issue was.
 

The UAV is only more complicated in some installs compared to others. The normal process for a sixer and other consoles with the 4050 buffer on them, is to install the UAV onto a socket that you either replace the 4050 with, or in the case of the sixers you have to solder the socket to the top of the 4050 IC. The 4050 in the sixers also controls part of the fire button trigger signals so it is critical in these older 2600s to keep it in circuit. 
The point being, you can purchase predone plug in versions of the UAV. (They cost more of course), but then you only have to solder in the socket and then just plug the UAV into the socket and run your output wires.
As for the quality of the output. The composite output is more consistent and of a better quality than most of the other composite only kits I've seen. The s-video is where the UAV really shines. However, the UAV was originally designed for the 8-bit computer line and as such, the color output from the UAV on the 2600 and 7800 isn't quite 100% accurate. But most people are not going to notice this. An example is that that some shades of green will appear much darker through the UAV than normal. A really good example of this, is the game Pitfall! where the tree trunks are a brown color through RF and most other kits but due to how the colors are handled and processed through the UAV, the tree trunks look more black. A small price to pay. 
I also make the argument that using the plug in version isn't as friendly because you still have to set the jumpers to the right position and can be goofed up, plus the extra cost I'm not sure saves me that much more time compared to just soldering in a few wires and having more flexibility in how I install it. I do use the KIT version for the 5200 installs as that does save quite a bit of time. But I purchase the DIY kit vs predone as I only use the socket, PCB interconnect header pins, and the terminal block for the output wiring. I do NOT install the jumper header block as it is MUCH easier to just solder a few jumper leads to create the jumpers I need vs all 20 of the tiny pins for the header block. The point of the header block is to allow you to swap the UAV into other consoles, but I'm not likely to do that. Removing it and reinstalling it just weakens the socket connections so I just buy them and keep them in the consoles I set them up for.
The UAV really isn't that difficult to install. The easiest mistake I see made (Because I still do it myself from time to time), is soldering the wrong wire from the UAV to the resistors or soldering the wiring on he UAV to the outside vias vs the inside vias as they could be marked a little better to let people know. Even just putting small circles around the vias as silkscreen would help with that. But I can't make design changes to the UAV.
