having a weird issue with these patches (only tried on fire red for now) original rom HASH matches and works well on real hardware. using Easyflash 5 gba 3-1 cart (NOR FLASH mode).
However the patched one starts with the regular tutorial about controls, then when it's supposed to transtion to prof oak all I get is a silent black screen.
edit, stumbled upon the older firered revival patch and it works just fine.
