As I am currently working on Umbral Genesis alongside Ramdemann and Optomon, this MMC5 patch brings wonders to the table!

I would definitely suggest the creator change the info on the IPS patch here to tell everyone that you have to expand the ROM itself instead of keeping that info within the readme file and what course to expand said ROM instead of just saying ‘expand’ it. The Castlevania ROM has to be prepared in more ways than one in order for it to even remotely accept this, especially if you want it to NOT be 100% reliable on FCEUX like how I’m doing. If you have done that properly, or found a programmer (or programmers) that does know how to expand things to work on all other emulators then you have the entire world of MMC5 by your fingertips as this mapper literally turns Castlevania 1 into Castlevania 3 (credit goes to Ramdemann for those words) as whatever is in Castlevania 3 can be placed into Castlevania 1 then or even entire new encounters altogether!

Plan your project accordingly when you mess with this MMC5 patch. It will open more doors than what you have originally realized. Have to re-plan everything which is no big deal :)

….though, for this to be accepted in Stake? That’s another story.
