  1. I have both chips for the fixed 7800 Impossible Mission. While they fixed the original bug they introduced a new one. The new bug involves the bonus game that gives you free items when you win. After a couple rounds it will tell you that you entered the wrong sequence every time. Even if you got it correct. That may be the reason it didn't get released. I posted the ROM out on the internet a few years ago, if anyone wants to try in an emulator. Also, Commando used a Pokey sound chip but no extra on cart RAM. It's great to see this stuff, I hope you can find more working games. Mitch
  2. Also worth mentioning, I checked a 7800 Motor Psycho proto I had near my desk and the number 2 EPROM is in the upper position. Mitch
  3. I am pretty sure those Save Mary EPROMs are for the 2600. If you look at the edge of the chip you can see the bottom half of the text AM2764. I have a set of 2600 Save Mary EPROMs and they have the same text. They are 8KB chips. For the PAL 7800 games, are you testing on a PAL 7800? PAL 7800 games won't work on a stock NTSC 7800. You can swap the NTSC BIOS with universal "Asteroids" BIOS and then they will play. Nice find on the Road Riot 7800, I hope you can find the other half of the game. Mitch
