After some efforts I finally got a little skeleton file of my own, obviously based off of tokumaru's. I would use his but eh, for originality's sake. Or at least the sake of "disguised plagiarism"...eh, who cares. Gotta say though, part of what was keeping me from the NES was the fact that...

As I said, that could be true, but it doesn't cause any problems or noticeable lack of speed, so.

I've never found the Master System to have a slow CPU, especially because of how big an interrupt routine you can fit into one frame. Speed isn't something I think you'd want to look for in 8-bit machines, anyway.

https://github.com/NicklausW/sudoku-sms This post is fairly late, but I felt like pointing out that Sudoku is now also on GitHub, cuz why not. I've been wanting to experiment with the NES, and have a small dev environment set up with asm6 but man, this is WAY different from what I'm used to. Somethi...

Update, 0.2 is out. Now there's 127 puzzles, along with some other changes. Check the link in the first post or in my description to get it.

The speed of tiles being copied into VRAM depends on how compressed they are. When uncompressed, it's very fast. You don't have to change the actual tile to flip it, though. Explanation is further below. Now, I wasn't ever big on Sega until I tried getting into assembly programming. I found tutorial...

I'm gonna take your little chunk one piece at a time. (Gonna ignore the MAME part, cuz I know nothing about that). I didn't know you were a SMS guy. It's pretty much my main console. XD but sprites not having flip bits and no vertical line per line scrolling kind of dampens it. Yup, I suppose so. At...

Once again it's for the SMS. There's only like 5 puzzles in the game right now, but I plan on writing a program to generate somewhere around 700 of them.

Enjoy.

Update: although I did this a little while ago, Pong is on GitHub. Think the link in my signature is broken...

My main project now: Sudoku. Wish me luck. So far a bunch of random numbers between 1 and 9 are on a grid, just need to do things from there?

I thought SMS games went into a loop constantly reading the lightgun until it registered a hit, then checked the beam counter value at that position? (better than the NES that doesn't even have a counter) In any case you should be able to read its value constantly as far as I know. That sounds abou...

From what I can tell of a document from SMSPower, the registers $7e and $7f can constantly be read for the pixel. Vertical (?) and horizontal, respectively. EDIT: It seems not so, if you're trying to put a trigger on the screen...looks like the ports can only be read when the trigger is actually fir...

What do you mean photodiode, though?

They've got two WLA-based demos and one SDCC-based one.

Thankya so much. I can't stand RGBDS, it seems like every piece of code I see written for it is always just...sloppy.

You can find it in my signature, or here's just the link: http://www.smspower.org/Homebrew/Pong-SMS I'm thinking about making Pong on the GB to make all the Nintendo peeps happy, but while Z80 ain't hard (as proven by the game this thread is about,) I just don't get how the Gameboy works for the lif...
