There’s nothing stopping you. Just know that the less accessible the platform the less plays you are going to get…

note for myself: markdown doesn’t work here :p

It’s fine I just wanna do something different than all the other competition members! thanks for the reply’s guys means alot!

I will be seriously impressed. I wrote an Atari 2600 game in 6502, and just about lost my sanity in the process. I would love to see a game jam entry built with 6502, and I would definitely be willing to download an emulator to play it. Go for it!

I’ve been studying 6502 nes machine code for quite some time now and i feel like its a good thing to do 😀

There are many emulators to choose from, it all depends on the system you want to use. Many popular systems you can choose include Nintendo, Atari, C64 (uses an enhanced version of the 6502). Whether that’s fine or not, I would guess there’s no problem if you’re only doing small non-commercial stuff.

Of course I would only recommend making a game for those platforms just for the sake of being different, but remember that people will need to download an emulator to play your game and configure the emulator, which is a big turnoff. Not only that but you’ll also need to invest way more time developing the game engine, time that could be used to enhance visuals, sound and complex game mechanics. There are other drawbacks. Emulators aren’t perfect representations of the hardware, so get ready to battle strange and undesirable bugs. Finally, unless you are already familiar with the system architecture, you’ll have to do a lot of homework first.

There is not game engine for the NES. It’s all internal and Addresses. The CPU and PPU are specialy made for making games. and it already has clock time. and Other enginey things. 😀

I wouldn’t say there aren’t game engines for the NES or that you couldn’t start with one. There’s is definitely repeatable code bases that are game agnostic like a sound engine, reading the controller, and even PPU update routines in NMI to handle updating name tables for scrolling that nearly any game can use. It may behoove you to have those things available before the start of the game jam as 48 hours goes by super fast. A

well like I said back there I would avoid anything that requires complex physics. Maybe something like an rpg, shmup, or a puzzle game. But if you’re comfortable and you have fiddled with the system long enough, then you can do a lot of cool stuff, imagination is the limit. Deliver something unexpected, an original take on the theme, imho that’s the whole point of the jam. Do not think that your game will be more special just because it’s on nintendo, the game is what matters in the end, so I would avoid cloning, like making another version of pac-man, space invaders, or any other overplayed game.
