Dr. Clipper said:That's probably the best compatibility setup you can have. If you have a bit more patience to do the WAD installations of IOS249, then this might be best:
IOS249 rev 19 base 38 (for installation apps)
IOS250 rev 19 base 57 (with ios=250 in config.txt for most games)
IOS223 v4 38+37 (select in per-game options for music games)
Config. USB Loader loads up much quicker when using IOS57 as the base.
If I were to use IOS38 for cIOS249 but change the config.txt to say "ios=250" would the loader boot using cIOS250 or just the games' IOS change to 250 within the loader?
