Technically if it is a truly PD (Public Domain) ROM you can do whatever you want with it, including sell it. Releasing something into public domain means that you relinquish all rights to the property. With freeware, the author retains all rights and therefore his/her permission would be required to...

Switch statements are rather inefficient for instruction decoding. Best way to do it is with an array of function pointers with the instruction being decoded as the index into the array. Flag calculation is probably the other expensive part, ASM won't help you very much there since the SH-4 doesn't ...

Out of curiousity, how are you dealing with endianness on mov instructions?

Only slight disapointment for me (and yes I know you are not programming this for me ) was the Sensible Soccer refused to start saying that is was designed only for a European Console. Used to love that game - still one of the greatest soccer games for any platform. The region lockout is a bit wonk...

Might be worth a try though. For now, I'm just going to try to modify what we already have. It might be possible to shift the FM or PSG over to the ARM, although Heliophobe said it was too slow to emulate the PSG (as found in the SMS), so... I find it hard to believe that the ARM in the Dreamcast i...

Mask of Destiny - Well, it has it's own video hardware, it's own sound hardware, and it's own CPU. It's not really a lot of hardware, but it's almost as much as the MegaDrive has in the first place. The video and sound hardware is substantially less complicated to emulate than that of the Megadrive...

The 32x has a lot of other hardware in it aside from an SH-2 There isn't a whole lot in the 32X actually. It has a linear framebuffer(well not exactly linear, you define the start position of each scanline) with 256 color indexed, RLE, and 15-bit color modes, a 2 channel PWM sound generator that pl...

It was one of the lame attempts by Sega to breathe life into the Mega CD, which was dead on arrival in Japan, and was doomed to the same fate in America. Still, some of the more interesting CD games were only released in Japan. (Lunar, for example). Both Lunar games were released in the US on Sega ...

Where did you hear that?

The standard C IO doesn't get allong with C++ IOStream. If you're going to use getch, you need to use printf and scanf instead of cin and cout.

Talk about emulation and homebrew on systems other than the Dreamcast, such as PC, GBA, PS2, GC, XBOX, etc.

This is an emulator that runs on a PC so it seemed most appropriate.

This is a currently unreleased emulator that I'm writing. It's been written 100% from scratch. Almost all of the SH-4 opcodes have been implemented (though I'm sure there are bugs I have yet to weed out), but not too much of the rest of the hardware has been implemented. I'll probably focus on the S...

The system isn't that hard to work with. Trying to take full advantage of all the resources available is quite a challenge, but you can achieve good results just by using the Genesis half of the system and that's not terribly complicated. The biggest problems are lack of interest and poor dev tools....

I heard a rumor that there was an app that would take your Genesis roms and put them into a Sega Cd image for you to burn and play on your Sega CD. Is this rumor false? It seems like it could be possible, though. The rumor may have been referring to SLO/buildscd ( http://www.retrodev.com/ ) as they...

such as the reproduction cycle of the anteater for example Depending on what he wants to do, maybe it's more useful to learn algorithms to make 3D engines, for example (suposing he doesn't already know). But I don't know neither his skills nor his future projects. Assembly is still a very relevant ...

The SuperH is quite different to the x86 line; however, the basic principles still apply to both. x86 gives you more flexibility with instructions, SuperH gives you more registers.

Bill Gates is not proposing that anyone pay for e-mail with money. This is just a case of bad reporting. Read the article on http://www.arstechnica.com/ to understand what he actually means.

I wanted Sega Channel so bad when it came out, unfortunately we didn't have cable at the time. I remember the X-Band as well, but I never really wanted one.

I think that you might need to go... to the right.

Ah ha! I'm an idiot. Thank you very much.
