Re: NES Game Project #1

I actually did quite a bit of research on the arduino dev cart thing... I would steer you more towards a Ram cart or nvram or fram or something, it turns out its usually quite a bit more complicated to actually 'program' most Eprom/eeprom/flash chips than to simply load some battery backed ram with...

Re: NES Game Project #1

Sound thinking.

For now this is strictly for fun, but since we are planning to make real cartridges to sell and/or give to kickstarter backers I think that we might directly ask Nintendo before taking the plunge.

So it hasn't been discussed much on the forum much? Kinda surprised if so.

Re: NES Game Project #1

Just posting a quick question; can anyone point me to any forum threads that talk about the legality of self-publishing unlicensed NES games?

I wanted to know how legal it is to sell them for profit.

Re: CPU budget questions

There is really short period when the VRAM access is possible - ~2700t, and 513+ are needed to do sprite DMA. So, if you need to put many values into VRAM, you have to write this part in assembly. Even further, you should prepare the values before getting into NMI, and use unrolled loops. If you ha...

CPU budget questions

In my experiments last night I tried to update the attribute table for a single screen with 64 random values. Boy was I in for a surprise - 64 random values within the vblank is out of the question for the NES. Glitch city. I was able to make a for loop in C that wrote 54 immediate values without gl...

Re: NES Game Project #1

Welcome! He's going to be creating a pair of homemade "dev kits" interfacing the computer via an Arduino functioning as an eeprom program through a cable going directly into a NES cart. I'd be curious to see how he overcomes the speed problems associated with this idea. CHR-ROM is pretty ...

Thanks so much man - would have never figured that out myself. I'm posting my new runtime.lib file, which I tested and it totally worked!

NES Game Project #1

Hi everyone, New here. I'm embarking on a side project to create an original homebrew NES game and self-publish a small run of physical cartridges. I have a lot of background in game design and assembly programming, and love working directly with hardware. I've developed things for GBA (example game...

Re: Programming NES games in C article

Hi, new here :) I'm impatient so I'm posting my urgent question first, will figure out where to post my introduction in a minute... Shiru, I'm trying to use your library with Nintendulator DX v34 which requires a newer version of the debug files, so I'm trying to compile a new runtime.lib with the v...
