Re: Unable to change mirroring in JY-120A

Ooook, just looked at that older doc. That explains everything regarding 35.

Guess I'll stick with 209, just wish wram was a function.

Edit: just saw your edit, would I have luck getting in touch with one of the fceux devs on having 35 worked on?

Re: Unable to change mirroring in JY-120A

Ok, so im starting to wonder if FCEUX is missing features to some of these mapper variations from JY-120A? I'm learning how to use extra 512kb of PRG-ROM. When i'm on mapper 209, these are the abilities im able to perform... Header is NES 2.0 1: set PRG-ROM swapping to 16kb for $8000-$BFFF & $C000-$...

Re: Unable to change mirroring in JY-120A

Just messing around with it, but I can't figure out how it does the mirroring. Even when i set breakpoints to the mirroring register, it does snap when I load super Mario world. Never encountered this. Edit: I ditched the .unf format and went to .nes and I set the mapper as 209, and now the mirrorin...

Unable to change mirroring in JY-120A

https://wiki.nesdev.com/w/index.php/J.Y._Company_ASIC#Mirroring_Select_.28.24D001.29 The notes for mirroring say that $D001 is the register to perform the changes for mirroring. But I am unable to do so with doing this? I'm able to use the other functions of this mapper, like setting the prg-rom si...

Re: Looking for interchangeable PPU chips (palette specific)

I had 2 frontoaders eons ago, and they both produced different color output on the same tube TV I had. But my idea is pointless from what you described. Is there a way to modify the contents of the update .NES file for the hidefnes, so I can alter the palette settings for one of the selectable palet...

Looking for interchangeable PPU chips (palette specific)

When I sent my NES to be modded with the hi-def kit, I was told the ppu had was having difficulty with the hdmi, so I had REV G chip inserted. Growing up, the front loader I had, had vibrant colors. Now with PPU swapped, the colors look almost washed, and a slight difference in tint too. I've loaded...

Re: new to snes environment, have some questions.

I've got another question regarding loading long. Are you able to load a ROM value long, with X and Y? Opcodes I heavily used were B9####(LDA'Y) & BD####(LDA'X)

Can I do this with using long, reading values from other banks that other banks, that my loading code is currently not in?

Re: new to snes environment, have some questions.

Thank You! I used the bsnes debugger and stepped through my NMI, turns out it had to deal with how I had my REP's & SEP's placed near the beginning and end of my NMI. I made it so when the NMI starts (before pushing everything) that I set A,X,Y to 8-bits. Then, at the end of the NMI (before pulling ...

Re: new to snes environment, have some questions.

I'm still having stack issues. Within my NMI, the RTI is not returning back to bank $80 which I set it to.

Re: new to snes environment, have some questions.

I'll have to recheck my routine for $2104, I'm doing a double write, but it's storing at 2 addresses in oam, but I'm able to load a table for the values I want. There's a lot for me to digest and understand correctly, a bit overwhelmed a points, but as long as I get the results I'm trying to accompl...

Yes, STY, sorry I had a typo.

And I got the oam to write without dma, the info on the write register being a word helped!
