@mitu Hi & thanks for your answer i found this site which gives all the color codes :)

@Sebiohazard Can you give me an example - a game that doesn't work ? The info might not be on the scraping site for that particular game.

Please can you have the crc32 for level2.rom of the trs-80? In the doc file the link for download is old. Error 404. If can give me all crc32 for all bios? Thank you very much. Sorry for my bad english.

@xdrak Sometimes you can't see for looking! It's a pretty obscure emulator, not sure a lot of people on here use it. I use it for DRAGON32.
