GBC ROM flashing leads to logo lockup(Nintend-) about ems-flasher HOT 4 CLOSED

I don't experiment this issue. Have you tried the latest version? as it contains a fix to the menu to issue #14 that is may be related to your problem. Don't forget to type make to update all variants of the menu with the fix.

I've cloned the repository anew, installed according to the instructions, but the issue remains.
Different GBC ROMs from different sources were tried. None actually work.
I've also confirmed that regular GB ROMs work properly even with the Game Boy Color as is to be expected.

Dumping the ROM with --read and then loading that with an emulator just opens the menu with every entry saying MENU; the GBC ROM doesn't appear in the menu(probably because that would require the actual cartridge hardware).

The --title command shows that the GBC ROM is actually present, though.

You can test the dump with BGB. This emulator emulates the EMS card but you'll need to set the title to 'GB16M': rgbfix -v -tGB16M image.gb (rgbfix is part of RGBDS).

Also, what you could try:

Delete all ROMS with the exception of the GBC menu and see if the menu is launching.

Flash a GBC ROM directly without a menu. You'll have to compile a older version of ems-flasher, without multi-ROM support (commit d90fa3f).

After that, we will have to determine where the problem occurs by modifying the menu

Edit: BGB is a Windows program but work well with Wine

Actually some ROMs seem to be working correctly. I will reopen the issue if I can find the source of the problem.
