You can burn multi-session discs, that way you can test the roms without wasting too many discs. Or you could fit a drive capable of reading cd-rw and use those (which I did).
You can get a list by googling, N64 - All released Games.xls (you'll need MS office or Open Office) You can change the CIC boot code of a rom with motetIII.exe (in DOS) You change the boot code of roms to match the same as the one you use as your boot cart. So, looking at your non working roms: Lylat Wars (A) CIC-NUS-7102 Lylat Wars (E) CIC-NUS-7102 Banjo-Kazooie (E) CIC-NUS-7103 Banjo-Kazooie (U) CIC-NUS-7103 Blast Corps (E) (M2) CIC-NUS-7101 Blast Corps (U) (V1.0) CIC-NUS-6102 Blast Corps (U) (V1.1) CIC-NUS-6102 F-Zero X (E) CIC-NUS-7106 F-Zero X (J) CIC-NUS-6106 F-Zero X (U) CIC-NUS-6106 Diddy Kong Racing (E) (V1.0)(M3)CIC-NUS-7103 Diddy Kong Racing (E) (V1.1)(M3)CIC-NUS-7103 Diddy Kong Racing (J) CIC-NUS-6103 Diddy Kong Racing (U) (V1.0) CIC-NUS-6103 Diddy Kong Racing (U) (V1.1) CIC-NUS-6103 Yoshi's Story (E) CIC-NUS-7106 Yoshi's Story (J) CIC-NUS-6106 Yoshi's Story (U) CIC-NUS-6106 Blast corps should actually boot if your using Mario, which is a 6102 or 7101 boot rom. It might be a duff rom or a region limitation which isn't telling you on screen that the rom isn't for your region (Use S-Paladin for that) So in a dos prompt, you type, motetiii romname -mario to change those roms to a 6102/7101 boot code. Or type motetiii romname -info just to find out what boot code the rom is using.
Wow! This is very helpfull , I'm gonna try this right away;-) Ah , now i also see why Blast Corps didn't run , I use European roms ^_^ Thanks for the tips! BUT , I got one weird problem with Pilotwings , it gives me an error > EEPROM FAILED or something , doesn't matter wich rom I use.
