Just like tokumaru said: I use a variable that I set when a frameLogic is completed, on the nmi I check for that variable, if it is set I do nmi updates. I could count dropped frames if I enter the nmi and see that flag is not set, and counting dropped frames like this: Nmi: lda isGameLogicCompleted...

Mmm, I thought it had to be registered or something, my fault.

Or perhaps I misunderstood what you meant by "that rom".

Question is, is it copyrighted?

Avast ye. There be no infringin' on this ship.

And what infringement would be that?

BootGod wrote:Kevtris, I'm glad you mentioned you found this chip in Fighting Hero, which I guess is mapper 193. War in the Gulf can also use this mapper number fine. So the game already works in Nestopia and possibly other emulators.

Will you share that rom?

There are several instances where I don't feel the need to name labels. Now that I think of it, this usually happens with labels used to simulate FOR, IF, and other commands present in high-level languages. You don't really need labels to identify these structures. That's one reason why I use NESHL...

Yeah, that would be a cool to prevent save game erasures. I meant 8 KiB of PRG RAM at $6000-$7FFF, not battery backed CHR-RAM. As I read on http://www.nesworld.com/aladdindeckenhancer.php "What it does contain is the 8K of CHR RAM, a lockout defeating curcuit, just like a regular Camerica/Codem...

I was thinking about something mapper-independent.
And I could only think about CHRRAM-SRAM.
32KB SRAM + BATTERY would be nice with external switches on the cartridge to select the bank.
No gui or boot, only a switch on the exterior.

As in the Aladdin a Lockout defeat chip would be useful too.

As most NES cartridges have it's own CHRAM and maybe SRAM, wouldn't it be useful to have a expansion cartridge to only use one chram/SRAM chip? SRAM could be bigger than 8kb and allow switching on cart for multiple savegames. Something like an Action Replay that adds that functions and makes carts t...

I do object reversing + random OAM start address + advance OAM in 7 entries each frame

Megaman 6 writes enemy tiles on the fly before they appear on the screen.

hi, im new to all this, just started a few days ago. im using nesasm3 i have a problem understanding variables. i know they must go at adress $0000, but also the CHR goes there. i know that one is in the CPU and the other in the PPU, but how does the assembler know the difference? another problem, ...
