Re: C optimizations?

A C-level optimization is making sure everything is aligned and writing in 64-bit units.

Re: FDS header date fields

- FDSStick has rather "canned" read/write routines. You could potentially make this access OOB data if you felt like it. Or play with pulse widths and see how much you can theoretically squeeze on there. ... Strictly a pet project for my own amusement. If there's other stuff you'd want it to do, I'...

Re: Need guidance with nes to snes.

From the description where xba fixed things, you weren't clearing the high A byte. Switching to 8-bit mode does *not* clear high A, so if something else happened to be there, you just added 0x1 (0x100) to a random value.

Re: Zelda II - The Adventure of Link... SUCKED

Ocarina isn't laggy because Nintendo understands variable FPS is bad, and locks the FPS to what they can consistently achieve. This is why Paper Mario is 30fps even though most scenes in it could do 60. Low fps is not as annoying as variable, but it's still annoying, and for both Ocarina and PM I do...

Re: Zelda II - The Adventure of Link... SUCKED

Majora's FPS is clearly better than Ocarina's, even with better graphics, so it's clear Ocarina was just badly optimized.

I find all Mario and Zelda boring, though I did like Ocarina's Water temple :lol:

Re: 96kb FPS

I haven't looked. Ed64 has a SD card API, N8 (/pro) likely has something similar. Dig around in krikzz.com/pub.

edit: Remembered the Mega Everdrive Pro's video player also uses a similar API to access huge files.

Re: 96kb FPS

Plus that doesn't make any sense: if you're targeting the Everdrive, you can already access gigabytes.

I did a live stream video yesterday but the sound quality was echoing, so I'll just post some stuff I mentioned. -At one part you accidentally wrote $201a instead of $210a. -lda #$01, sta $420d before setting up anything else would only work if data bank is $00 and A register is 8-bit at reset, whi...

Re: 96kb FPS

Sure, but it would take an eternity in loading times. Even that had long loading times on a PC. It would also require a board with tons of banked CHR RAM and RAM, otherwise you'd get those loading times every level/whatever. A roughly comparable scenario is very advanced compression. Someone used rA...

Re: EverDrive-N8 Bank Switching issue

Well, even official carts have such differences, starting from the pins' lengths. "Game X always works, but Y and Z work intermittently" is common enough on cart console forums. Then ED pulls slightly more power than a normal cart.

Does anyone know if the Everdrive N8 Pro is incompatible with the CopyNES like its predecessor was? That's been the main question stopping me from getting one, but I never got an answer on the support forums.
The Pro has its own USB port. Why would you want to use copynes with it?

Re: EverDrive-N8 Bank Switching issue

While faulty ED is possible, it's more likely your console's pins are dirty.

You can find upload code in the manual, and in snesmod and gss code.
