So, the particular expansion was done by Djinn years and years ago and since this project is quite old, I completely forgot about it and I discovered it after the translation went through a round of testing. I really haven't tested on many other emulators, but it works on FCEUX. I mean support for other emulators is really quite trivial. All they need to do is allow an extra PRG bit to be available for the mapper. It's literally just a small change and the same thing goes for flashcarts as well. I say who cares there wasn't a board at the time with the expanded specs. The NES don't care about any of that stuff.
Anyhow, I'll make a note of all that when it's released and will provide source files to anyone interested in a mappper hack. If someone can hack the translation to be another mapper, I'll incorporate it into our work. Btw, someone did actually hack the Japanese game to be mapper 68, but it's not incorporated into the translation.
The same thing applies for Knight Gundam, which is another old project of ours. That uses mapper 185 iirc and doing a mapper hack for that one probably isn't possible. Again, really trivial to add support for the translation. As aishsha said to me if he had to choose being a purist over a full script, he would choose the later every time. I agree with him 100%.
Funnily enough, my Megami Tensei translation also expands the ROM past the mapper limit, but that is supported by flashcarts etc and other emulators like puNES. It highlights my point on how trivial this stuff is.
Now you have the Final Fantasy 3 translation where the mapper was changed to MMC5, but the hack is buggy. It would be much easier to just ignore those dumb limitations and make the ROM however big you want.
I am very much looking forward to playing your team's patch when it is released. I was just reading Peter Barnard's translation of some Metal Slader Glory interviews over at Shumplations and I'm even more excited to finally experience this interesting piece of HAL's history. Are you guys planning on releasing the patch on or around August 30th? Would be fun to have the patch released on the game's 27th anniversary.
Anyway, good luck on this and all your other projects, announced or otherwise.
I didn't know about the release date thing, but I don't have an exact date in mind. Btw, Peter Barnard is the translator for the game, if you didn't realize it.
I'd also like to point out it's currently not possible to play Metal Slader Glory on hardware due to no board existing that can handle the PRG-ROM size, which was expanded to 1MB and also happens to be the max size limit of an MMC5 game. I might be talking out of my ass here, but I bet someone could design and produce a board/flashcart that could handle a 5MB NES ROM. Sort of like a MSU-1 version for the NES.
