    Mega/sega Cd

    Concerning Sonic CD, be sure to get the Japanese version. It has far better music than the US version. The European version has the same soundtrack as the Japanese version, but it plays considerably slower at 50 fps. The Jap version therefore is the superior one.

    Vectrex Emulation?

    I'm a bit late for the party, seeing how my last post here is almost two years old, but I suppose late is better than never. I never did get round to work on Vec2X again, and as time went on I more or less forgot about my whole GP2X. Recently I dusted off the little machine again, refreshed all...

    Vectrex Emulation?

    Hmm, I have been a bit absent lately, haven't I? Time does tend to fly, even when not having so much fun. In any case, I am currently very much suffering from Real Life™ Syndrome, due to a graduation project that has just started. This means full working days, and little time or will afterwards...

    Vectrex Emulation?

    Ahh, I missed that. Thank you for pointing that out to me :)

    Vectrex Emulation?

    Tried 'em, they work just fine. Those overlays are a bit pixellated though, and not as pretty as the GIF versions. But if it's compactness that you're after, then they will work just as well.

    Vectrex Emulation?

    Stability seems to be okay, there are probably still a couple of bugs left, but most games run fine. Speed is, well, that's still one of the biggest hurdles. Right now one emulation cycle takes about 70 ms, which should be at most 20 ms for real Vectrex speed. Overclocking the CPU (a feature...

    Vectrex Emulation?

    Progress on Vec2X has been kinda slow lately... mainly due to Real Life™ interfering. I did manage to get a couple of features in though. First of all there's a whole plethora of screen size options. You can play it normally with the screen horizontally orientated, in either normal aspect ratio...

    Should I Get A Gp2x?

    Take a look over here. Works on any OS that has USB support and a telnet client, which is pretty much any OS you can think of.

    One Must Fall 2097

    Yes, that is known, but they don't give any reasons for it. The only reason I know is because Rob Elam (the game's programmer) thought OMF2097's code sucked and not worthy for public release. But that's a stupid reason, because that problem will solve itself when the code is released. I suspect...

    One Must Fall 2097

    It's so stupid that they won't release OM2097's source. The game's a cult hit in the truest sense of the word, so there are god knows how many people who would like to see an enhanced port to their favorite system. The GP2X is an obvious target, but you could also think of commercial releases...

    Must-have Emulators?

    Yes, the Genesis and Megadrive are both a must...

    Vectrex Emulation?

    Well, not to burst your bubbles or anything, but getting the emulator to run on the GP2X was the easy part. Getting it to run well, that's the hard part. I don't know much about the inner workings of emulators, nor do I know much about low-level optimizations, so it's quite the challenge. It...

    Vectrex Emulation?

    Two hours in and I already have a first prototype running on the GP2X, as you can see here: (Click on the image for a larger size. Don't mind the speckles, my digital camera sucks) It's not quite fast yet, running at about half the normal speed. First I'll try to eliminate all the integer...

    Vectrex Emulation?

    Yes yes, drawing vector graphics is no problem on a different aspect ratio, that wasn't my point. You'd still get a pretty squashed image if you keep the screen at its normal orientation. Of course, you can hold the GP2X at a 90 degree angle, but I'm not sure how the controls would work out...

    Vectrex Emulation?

    Hmm, that emulator seems simple enough. The OS dependent code is nicely separated from the rest, so porting it to the GP2X should be pretty straightforward. Controls should map to the GP2X nicely too. The only problem I see is that the GP2X's screen isn't very well suited for the vertically...

    GP2X Video Based On Gp2x Basic Programming

    This might not be such a bad idea. For many would-be programmers, the first steps are usually the hardest, and learning from a video works much better IMHO than reading a tutorial. You actually get to see how every little detail of every step goes, instead of blindly following a step-by-step set...

    Moving An Image Around With Sdl

    What Alex here says is more or less true, but that's not the real problem here. An SDL_JOYBUTTONDOWN event only fires once when you're pushing the button down. Holding a button down won't generate any more of these events. That means you have to move the button back and then push it down again...

    Help Loading 8bit .act Palette Files?

    I've tried it here now, and it seems to work just fine. Here's the code of my little test project: ACTTest.zip. Also includes test image and palette files, Windows binary and Dev-C++ project file.

    Help Loading 8bit .act Palette Files?

    You can pretty easily see how ACT files work by opening one in a hex editor. It's just a bunch of plain RGB values, one byte per color channel, one RGB sequence for each of the 256 palette entries. 256x3 bytes makes 768 bytes in total. No header information, compression or other difficulties to...

    C Or C++

    The most important thing about learning C++, in my opinion, is to realize that all of the OOP stuff is nothing more than a series of compiler tricks. What this means is that every C++ program you write can be translated into an equivalent C program without any loss of functionality. Inheritance...
