I gave Worms Battle Islands a try with cIOS 251 [58] with all 3 loaders. WFL & GX both start the game up but the title screen freeze. I got same fragments ID mismatch error using CFG with base [58]. CFG surely has a problem with Base 58.
Thank you.
Then maybe Hermes cIOS223 with Base 37 -v5.1R is the only one working for it.
