Describe the issue.

Unable to dump "Tetris Color" from the ModRetro collection.

The name does not show up and it creates a sdcard://GB/42 folder but not an actual dump of the cartridge. This also happens with Hermano, similarly. The other ModRetro carts that have names work fine and I can get a .gb file from them.

Try adding this check to here:

if (myLength == 0) {
  // rom name unknown
  romName[0] = 'U';
  romName[1] = 'N';
  romName[2] = 'K';
  romName[3] = 'N';
  romName[4] = 'O';
  romName[5] = 'W';
  romName[6] = 'N';
}
