    GP2X 68000 Assembly (asm 68k)

    Doom ran really well on a P60 with 16MB of RAM. Difference? Roughly 99 MIPS and about 15.9MB of RAM. Of course you can program a PC game with C. But then, a P60 was perfectly capable of running Mega Drive games in an emulator. The difference in raw processing power between the two is like...

    Gp2x-dragon: A Dragon / Tandy Coco Emulator For Gp2x V1.0.1

    Does this port support cassette files? I didn't have a disk drive for my Dragon, so all of the games I've converted are in .CAS format. If it does, where should the .CAS files be stored, and how do you load them? Looks like a great port, though! EDIT: (Digs around in the source...) Tape...

    GP2X 68000 Assembly (asm 68k)

    I'd be amazed if the developers were writing anything but pure 68k asm already. Coding videogames in high-level languages is a relatively recent phenomenon. Pretty much any commercial game will have been written in assembly prior to the advent of the 32-bit consoles (N64, PlayStation, Saturn)...

    Gpfrontier - Elite 2: Frontier Ported To Gp2x

    The autopilot was buggy as hell. This was my trick for landing correctly every time: - Use the solar system viewer to select the spaceport you want to land at as soon as you decide to travel somewhere. - Enable autopilot until you're pointing in the correct direction. - Switch off autopilot...

    Gpfrontier - Elite 2: Frontier Ported To Gp2x

    According to the readme, the code is a port of another guy's work - he disassembled the ST version and rewrote it in C: http://www.tomatarium.pwp.blueyonder.co.uk/glfrontier.html Regarding speed, it's quicker than an A500; probably about the same speed as a standard A1200. Nowhere as fast as...

    Gpfrontier - Elite 2: Frontier Ported To Gp2x

    Brilliant conversion, but there needs to be a button that switches the d-pad from controlling the joystick to the mouse. Controlling both at the same time is a clever solution, but it doesn't really work - in the stockmarket screen, for example, pushing down in order to click one of the boxes...

    Populus

    I've got the Amiga, SNES, Mega Drive and Master System versions on the original platforms, and I recommend the Master System version, to be honest. It's got the extra worlds introduced in an Amiga expansion pack (the Bitplanes levels, for example), plus it's got more levels than the others put...

    Oh Dear....teething F200 Troubles!

    The "mapping dots" are spacers that separate the two layers of the touch screen. The touch screen is activated when the two layers connect (occurs when the stylus is pushed against the top layer); the spacers keep the layers apart until a force is applied. They are a necessary feature of this...

    Corn N64 Emulator Mystery

    If the emulator ran that quickly, you can guarantee it was 100% x86 assembly. Ain't no way no how that's going to be ported.

    Oldplay V0.8

    I've had a quick play with this, and it's superb. Just a couple of bug reports. SCUMM music (I've tested the Amiga Zak McKraken music) crashes the player, as do all but one of the OctaMED tunes I've tried. I know that there is a bug with OctaMED V4's save routine that can cause MEDs to crash...

    New Project

    Think you've hit the nail on the head there. The GP2x is powered by two 1.5V AA batteries, giving a total of 3V in the entire machine. Now, how exactly is a 3V handheld going to supply 5V to its USB port?

    Is This The Xgp

    Argh, it looks like a PSP crossed with an N-Gage with yet another shitty joystick. When will they learn?

    Problem With Drmd (sega Emulator)

    Ah, that explains it! Thanks.

    Problem With Drmd (sega Emulator)

    Got a problem with DrMDx on my GP2x - the menu flickers like crazy. Not the background; that works fine. Just the text over the top. Is this a known bug, or is it specific to my GP2x?

    Gp2x Joystick Exposed - The Internals

    Street Fighter 2 on the first SNES emu works really, really well with the GP2x. All of Ryu's moves are easy to perform because it's so easy to hit the diagonals. Pretty much everything else is a chore, though...

    Fuse2x (spectrum Emulator)

    Spectrum games all tended to use the same joystick port. The main reason for this was that if you loaded a game up with the joystick in the wrong port, removing the joystick would wobble the joystick interface in the back of the computer and it would crash. Very early games are the exception...

    Gp2x Joystick Exposed - The Internals

    Ok, the problem is that the hat is circular. Consider this picture: The red circle represents the contacts. You hold the hat at such an angle that the blue arrow is in contact with the red circle. On the standard hat, a circuit is made with the top-left diagonal, despite the fact that...

    Gp2x Joystick Exposed - The Internals

    It's past one in the morning now, so excuse me if this doesn't make any sense. All of the posts so far have been concerned with the contacts - how to re-orientate the joystick so that the large contacts are at 0 and 90 degrees; or shortening the large contacts; or lengthening the short...

    If they open sourced the firmware they wouldn't need to. *ducks*

    Favourite Genesis Games?

    Syndicate is an isometric cyberpunk-esque shoot-em-up. You contol a team of 4 cyborgs who have to roam around various cities blowing up cars, shooting people, persuading people to join your syndicate and researching new technologies. On the Amiga and PC it worked really well - you controlled...
