Still fun to play after all these years =)
I forgot to mention it here: Gakken Invader was added to MAME a week ago
This one is cyan-only. There's also a version with a 2-color VFD. Anyone has it? I want to see if the VFD segments are the same(and it's only the colours that differ). And a photo of the PCB to see if it's the same MCU serial.
