Re: issue with super mario bros sprite 0 xy, when reading $2007

I have another issue. There's an unrom game I was messing with that always has an active Sprite 0. I wanted to do a simple tile write to the nametable. I didnt want to add additional code to the games original vram routine, just so I could already be at 246 scanlines, so I tried doing BIT $2002 BPL,...

Re: issue with super mario bros sprite 0 xy, when reading $2007

i tried that, but it looks like sprite 0 dissapears, meaning the entire screen for a split second looks like the entire said NT, whether you are on $2000 or $2400. Not sure if my order of things happening is the issue?

My code works, the bits i need modified are done so correctly, but i keep forgetting how to handle $2005 when my routi...

I heard Mesen was incredibly accurate to a real NES. But other than that that's all I've ever known of it.

Re: Need help with mmc5.cpp source, for custom modification

I would love a register to enable both CHR-ROM/RAM. Maybe an FPGA MMC5 in the future with enhanced features?

Re: Need help with mmc5.cpp source, for custom modification

Do my current changes look ok? Especially my changes to & 7 ?

Any further assistance would be great. I can't progress any further with this, not even sure if what I've done is correct.

Re: Need help with mmc5.cpp source, for custom modification

Thank you rainwarrior, I'm going to start making adjustments/changes the best I can. EDIT So these are the changes I've made, but still no luck with swapping newer pages. I do however have the .sav outputting perfectly at 256kb. BuildWRAMSizeTable(void) for (x = 0; x < 32; x++) { //infidelity 11-12-...

Re: Need help with mmc5.cpp source, for custom modification

I'll edit that tonight. I know there's another section that looks to deal with the actual swapping of pages. They were "case"'s

case 0
case 1
case 2
case 4
case 8

I tried fiddling with that area but wasnt getting the correct results. Shouldn't have expected much since I can't write c++ :-/
