Hmmm, So then I guess my method may just be for nigh then. Compatibility is important, and I can already think of alternative ways for what I want to do without reading from the PPU.

Thanks guys!

Re: Reading Palettes via $2007?

Is this on hardware or on an emulator? Have you tried multiple emulators? Good call, other emulators are having different effects. Was using FCEUX because of the monitors, tried Nestopia with a better result. I will bust out the flash cart when I'm home from work. so those $3Fs you have in the spri...

Reading Palettes via $2007?

Anyone have the secret sauce on reading palettes from the PPU via $2007? I know it is not buffered like normal reads from VRAM since palettes are stored on the PPU itself, but everytime I try to read palettes to save in RAM, I get values from my name table. I'm doing this in my NMI with other graphi...

Re: Zelda Compilation Album on Cart

Re: Zelda Compilation Album on Cart

Have been unsoldering mask roms to take a break from mml and coding for the time being. And then with boards ready and waiting, I decided to wire up a socket and do some hardware tests. _While there where issues at first_ Wiring confusion: 27C010 vs 27C512 (Solution = lift and ground pin 22 (OE/Vpp)...

Re: First post! EPROM Substitutions and Pinout Confusion?

Looks like pin 22 on the 27C512 is in the same spot pin 24 would be on the 27C010 so wiring pin 22 to GND is sort of working on console. Though my program is pretty broken now. Not sure if just more wiring error or something else. *Scratches head*

Re: First post! EPROM Substitutions and Pinout Confusion?

27C512 only holds 64 KiB; few games have exactly that much PRG. (For whatever reason, NES games usually had 32 or 128 KiB of PRG, but largely skipped 64 KiB). You may be better served either ignoring half the capacity, or making a multicart. For 28-pin sockets, the NES pinout matches the standard; ...

Re: First post! EPROM Substitutions and Pinout Confusion?

I'm working on an UNROM board. Have a bunch of 27C512 chips around (28pin) . would these need the wiring suggested here? pin 24 to GND? Not really 100% on what chip this re-wire was meant for. I beeped it out and Pin 24 on the 27c512 is A9 rightly going to NES cart pin 4.
