SpritesMind.Net

I guess it must be my internet service. I used internet at someone else's house, got on Spritesmind OK. And they were on a different provider from me. Pretty strange.

Actually the Sega Genesis hardware indeed offers a single PCM channel through FM channel 6 (YM2612) but you have the Z80 CPU dedicated for sound so you can somewhat do software PCM channels mixing to have more than 1 PCM channel. That is exactly what the XGM driver does, it spent about 70% of the Z...

Not only am I a Gendev noob, I'm a sound and music noob also. (And a graphics, animation, programming, and maths noob, but that's beside the point. 8) ) But noob or not, sound matters a lot to me. It's really the main reason why I decided to learn Gen/MD programming: access to an awesome synthesizer...

Still having issues accessing Spritesmind... :( Yes, I too am having this same problem. I'm also in the USA, and recently have only been able to get to either the site or the forums with a VPN (using it because this is a uni rental laptop, and I don't trust the university. Don't want to give them an...

I've been unable to access Spritesmind for a few days now. Doesn't matter if I browse to the forum or to the main gendev.spritesmind.net URL, either way my connection always times out. I tried both FireFox and Chrome on my PC, and I tried browsing on iOS, but I get the same connection time out error...

Wow, this looks great! I'll have to give it a whirl sometime. Thanks for making this!

While I'm at it, your game, Tanglewood, looks really good as well. Can't wait to see the finished product!

... Never test with Fusion or Gens as they are horribly inaccurate. .... I'd just like to add that, while they're perhaps not "hardware-perfect", these emulators works great on almost any machine, not only with the last intel xxxCore. So yes, it's a choice between accurate and usable but for basic ...

most developers are sensible enough to have the games able to run on NTSC and PAL systems as is, even if they have region locking (Sonic 3 and Sonic & Knuckles for example are like this), however some specific games or game companies may have had different policies regarding to this and having sepa...

Checksum is for a simple integrity check. The game does a check on itself and typically shows a red screen when the freshly made checksum doesn't match with stored one. Also checksum often is just a counter, where each word of the ROM is added as 16-bit integer, and it does this from 0x200 to End o...

Region locking is always software implementation. That's interesting. So unless a Gen/MD game is designed to be region locked, there's nothing stopping you from running it on any version of the console, be it PAL, NTSC, Japanese, European, whatever? (I haven't looked into region issues much yet. I ...

I doubt anything in a real machine would try to reference any of the data in a meaningful way. only the pointer to start of code, and SEGA at $100 are required. I thought maybe at least the country codes at $1F0 ("J" for Japan, "U" for USA, etc.) might be needed by the hardware for region locking g...

I came across the source for a Genesis pong game by TmEE that doesn't use the standard ROM header described in Sega's docs. In fact, TmEE's code just writes a bunch of text over everything that's supposed to exist from $0..$1FF, with the exception of the code start address at $4, and the TMSS string...

I like assembly, but I also like BASIC. I hope your project is a great success!

Probably not useful info, but running your test in different emulators gives different results. Shocking, no?

That's more or less it. I really appreciate you taking the time to answer my questions about this! I think there was a proposal to either start a wiki or start using one of the existing ones to collect documentation. Don't remember what came of that discussion. Man, that'd be great! Obviously, I do...
