Bootgod's database has a search feature for answering that kind of question:

http://bootgod.dyndns.org:7777/search.php?romsize=256&&ines=1&battery=Yes

That would appear to include SKROM games with 256 KiB PRG + 128 KiB CHR, which is why I added &vram=8 to my query a few posts up. Yet your results are the same as mine. I'm surprised that there aren't actually any 3 Mbit SKROM games.

Although I didn't decide yet whether we have been a licensed or an unlicensed developer.

Given how close to UNROM the Codemasters board behaves, I imagine an unlicensed developer would more likely have gone with a custom UOROM+WRAM board.

Ah, whoops. Sorry for the redundancy, I probably thought I was at the end of the thread at the bottom of the second page when I hit reply. :P

DRW, I can understand not using battery-backed CHR-RAM if you're trying to be period-accurate, since no matter how simple/cheap it is, this solution was never used by licensed games, but your "prejudice" against UOROM is exaggerated, considering that any UNROM board can support 256KB with the addition of just a few wires, and that a few licensed games did use that configuration.

Well, this isn't an issue anymore anyway. We do MMC1 now because of the battery save. So, I don't need to think about whether UOROM would be acceptable for me until I do the next game.

Sure, I know you've decided on the MMC1 for your current game, so I was indeed talking about UOROM for future projects.
