GBC Pokémon crystal MBC30 question

Post by Markfrizb »

I know that the MBC30 in a Pokémon Crystal can accommodate a 4mB rom (compared to the normal MBC3 which can only accommodate a 2mB rom). My question is, are there any hacks or games that are bigger than 2mB where the MBC30 would be necessary to run those game hacks?
Thanks!

I heard of a Pokemon hack using it. Pokemon Coral which looks like a hack of Pokemon Crystal.

MBC30 also offers 64 kB SRAM compared to MBC3's 32 kB according to my notes.

Right, the sram on the cart is 1mB (128kB) but A16 is just grounded leaving only 512k (64kB) available to the mapper.
Oddly enough, there are some MBC5 games that also have a 1mB sram on it.
I’ll look up that hack, thanks for the tip.
