Cheers,
what a wonderful site! I would be hyped to contribute a short
decoder for the VisualBoy/NEC-PC CPUs (tested for VirtualBoy).
Assembler code is public here:
124 Byte long and depacking raw BLOCKs of 64KB with a 16bit size header
(similar to other low-end decoders).
Thanks for the great effort here!
