Is there a way for mmc3, to have chr-ram coexist with chr-rom? In Zelda, at $302 is where you can write to $0-$3F1F in ppu memory. But since i added chr-rom i can no longer manualy write to $0-$1FFF. Is there specific asm i need to write to pull it off?

The TQROM variant supports both at the same time, but I think you lose the option of sram.

I tried mapper 119 yesterday, but my rom crashes after either i press start at the title screen, or during the story when it shows the items in the game. I didnt know if maybe there was a way to disable the header during a jsr, to quickly load chr-ram.

The header for NES games is only there so that emulators and flash-carts can tell what hardware the rom is expecting. As far as the game is concerned, it does not exist.

Yeah i had a feelin on the header. I just figured there was a quick workaround. My chr-rom works fine, just sucks making copies of a ton of gfx, for when i just want to change 2 sprite tiles. Thats why i was trying to use $302 to write to $0-$1FFF.

It looks like Namco 106 also supports CHR ROM and CHR RAM at the same time, as an alternative to TQROM, (though it wouldn't be MMC3...)
