OpenTyrian is a port of the classic DOS game Tyrian to C using SDL, so it can run cross-platform without DOSBox. (Descriptin taken from http://code.google.com/p/opentyrian/ )

Changes:

* Non-fullscreen mode is now centered. See Title -> Opentyrian menu.
* ARM assembler sound mixer. Nice speed up, Pentium detail level is fully playable! Code is thanks to sweetlilmre and his efforts porting Tyrian to the Gizmondo.
* Improved controls within menus. No longer uncontrollably fast!
* Improved controls for accessing PAUSE and IN-GAME SETUP.
* GP2X specific readme-gp2x.txt providing instructions and setup.
* Redefinable fire keys. See Options -> Joystick menu.

This release is a full package! No additional files are required.

Shortly after Test 1 here comes Test 2 of ZODTTD’s PSX4ALL/PSX4iPhone port for the GP2x.

Release notes:

Here is the direct download link to psx4gp2x v0.1.2 Test 2:

It’s been a long time since a psx4gp2x version has been made, so the change list is very long.
I can tell you that the newly redesigned frameskip has been helping things a lot. Also the dynarec has been remade. Performance has increased quite a lot.

I just got done playing a game on my GP2X @ 266MHz. Buster Bros Collection, with sound on and interlace off, ran at 60FPS steady in-game, and the menus went way too fast, sometimes 120FPS. Frameskip works well on it’s various settings and due to the way it must be designed, it doesnt skip certain frames, so things are kept smooth even on really high frameskips. Wipeout XL is amazing to see! 🙂

While there is still more to be desired, this is pretty exciting news. So my todo list contains:
– Further improve the dynarec.
– Tweak some default settings so compatibility is higher while maintaining performance. Thing includes the psx cycle setting.
– Enable BIOS emulation option in the menu.
– Enable the use of external menu systems. 🙂
– Check if save states are working. Both save states and memory card saves are implemented.

ZODTTD didn’t forget the GP2x community and ported his recent PSX4iPhone over to the GP2x.

Release notes:

Hi everyone!

I said I’d be back with a release of psx4gp2x when I learned more from trying other platforms, and here I am…with a new build of psx4gp2x! (IMG:style_emoticons/default/smile.gif)

Keep in mind this is a test build. Think of it as a rough beta.
– There’s no pretty interface, as it’s the standard old psx4gp2x GUI. I will soon move over to allowing it to interface with a menu system.
– There’s no support for BIOS emulation (HLE) in this build, though it will be enabled in future releases. For now, you will need a PSX BIOS, either bios41a (I hear this is a great BIOS!) or scph1001.bin, but it MUST be named scph1001.bin (all lowercase) and be placed in the psx4gp2x directory where the psx4gp2x.gpe is.
– Save states may or may not work. Haven’t tested them yet.
– Memory card in-game saves should work.
– Lots of stuff needs tweaking.

If you really want to see how things improved, play Buster Bros Collection from the previous release and compare it to this one. I was playing a very nice game with this latest build with sound enabled (sounded good!), no interlacing, and frameskip 1/2 and it was great.

Remember this is based on psx4iphone private beta v0.1.2 which is implementing my modifications to frameskip. Some games get graphical glitches or prefer a certain frameskip setting. If you see a flashing black screen glitch, just change the PSX Cycle and make it lower until it goes away.
You will also notice that even on really high frameskips, especially in 3D games, things dont go much faster and are still fairly smooth. This is due to the way these games are programmed. Not all frames can be skipped in the render process, so sometimes a really high frameskip in these games gives a slight performance boost but still keeps things smooth. Help me find out what settings should be default.

Here’s a direct download link to psx4gp2x v0.1.2 beta/test build:

Installation is the same as previous psx4gp2x releases. Fairly standard stuff, but since I dont have it all written out right now, I’ll leave it to experienced users.

EDIT: I’ve set up a psx4gp2x section in my very active forums at www.zodttd.com. Though it seems its pretty empty currently.

Simple Dev Studio is a very small IDE for GP2x SDK (0,3 mb) for those who want to make small applications without the need of a +500 mb Visual Studio install. The IDE itself contains and needs only the official GP2x SDK and additional SDL libs or minimal libs to work.

Paolo ‘Neurox’ Borzini has released his Christmas gift tot he GP2X community.

Help Santa Claus to find some specific object. The game is in italian language, so if you don’t know italian, it might be a good opportunity to learn it 🙂
