Re: I accidentally discovered what Double Dribble was probably intended to sound like.

That's a bit confusing, if the track is silent, why do you think it was intended to be played back? What's the point in using up resources for silence?

Re: VBCC Optimizing C-compiler now supports NES

Just a note, if you intend to target SNES at some point, that "only one section is active" setup will prove problematic. On SNES, you may want code and rodata to go to different sections. #pragma section codebank1 // But where do the string and var go? Certainly not codebank1, I hope void foo() { st...

Re: Help with NES-001 Power and Modulator PCB

Recently there's been two or three "made from scratch" NES motherboard schematics. They expect the original CPU and PPU (or compatible clones) but use new components otherwise; maybe setting up one of those would be easier for you than reversing the old power board?

Re: Problems with F-Zero and Super Mario World

F-zero uses an expansion chip, maybe it pulls more power than your other carts. SMW doesn't use one though. Are your other 20 carts plain or with chips?

edit: Oops, remembered wrong. F-zero wasn't a DSP game.

Re: Standardizing symbols for PCB mirroring pads

Tokumaru's pic 3 makes me thing it's some supermapper that allows you to arbitrarily position the second nametable in VRAM.

Re: Cart/Box/Manual Manufacturing Options?

The three you mentioned as well as MegaCat can do the entire thing; send a ROM and the manual/box data, let them build and sell. INL also sells cart parts, several other shops do too, if you were to make the carts yourself. Box and manual can be done by most print shops. Etc etc. As your game is NRO...

Re: Official NES Homebrew Seal of Quality

Plastic molds still cost 10k+. Industrial-grade 3d printing is good quality, but you'd probably pay 10-20$ per cart, ordering from shapeways or similar.

Re: Replacing Liquid Electrolytic Capacitors With Solid Capacitors

Why recap the old voltage regulator instead of replace it entirely? I hear the modern replacements are quite a bit better.

Re: Shooting projectiles at the player from predefined angles

My angle functions are "accurate and full division", and they don't take massive time. I don't remember how many lines exactly, maybe 10-20, but that's still quite below the optimization threshold. Several enemies can shoot at accurate angles without the frame breaking a sweat. So perhaps measure a ...

Re: FROM BELOW (Tetris-like) [WIP NES Homebrew]

Writing in C does give you a headstart. It only took me a few weeks, when completely new to NES, to make a plants vs zombies style game. To profile on NES, use the color highlight or grayscale bits. Set it before and clear it after the code, and you will see on screen how many (rounded) lines it tak...

Re: SNES game PCB cartridge with chip vs battery to save

FM18W08 unit price: qty 1 28$, qty 1000 19$. Yikes, the only way those chinese can afford to put them in snes repros if they can pull them for free from some junked equipment.
