Greetings everyone,

I am curious to find out what it takes to make a repro of Akira for the FC/NES. I had thought that since the mapper, 33, is a bit on the odd side or at least uncommon, it would be hard to do. Well, to my surprise it looks like a few individuals are gearing up towards making repros of Akira and for a quite a price it seems. So would anyone know what materials would be needed and how much it would cost to make roughly? Thanks.

The mapper appears comparable in capability to MIMIC-1, the predecessor to MMC3. Perhaps the easiest way to repro this game would be to first hack it to MMC3, at which point the cost is the same as the cost to repro any other MMC3 game.

What about mapper 4? There is already an existing hack that converts the mapper to 4 for Akira. Does that make a difference?

Akira (J) [hM04][t1].nes
PRG ROM: 8 x 16KiB
CHR ROM: 32 x 8KiB
ROM CRC32: 0xdcb096a9
ROM MD5: 0x8a04b2495442ed9a63d43c870e7cf145
Mapper #: 4
Mapper name: MMC3
Mirroring: Horizontal
Battery-backed: No
Trained: Yes

Only FCEUX can run it. I don't know if it has any bug.

You'll probably want a new hack without a trainer.
