• Added MiNT definition file for cmake.

Image viewer and movie player for Resident Evil games.

• Add separate clock for engine, so loading times are not taken into account for player movements.
• Add timing in ms, in log file.
• Heavy rewrite for texturing. The background image is processed with same stuff as the model textures.
• Heavy rewrite for drawing code. EMD model is organized in a skel structure, with the various meshes.
• Can set width,height,bpp of video mode
• Software renderer: Bilinear filtering for background.
• Display model skeleton.

• Fixed some bugs in S-Buffer.
• Added 24 bits rendering to software renderer.
• Added room map with camera, camera switches and boundaries.
• OpenGL: Disabled ARB_npot texture support, till testable.

All games:

• README list supported game data files.
• Added -iwad /pat/to/gamefile.wad command line parameter.

Doom:

• Fixed bug when saving game, was corrupting memory
  (Thanks to Sascha Uhlig for report and testing).

The ports are built with SDL 1.2 (svn 20090526) which have the following things changed, compared to SDL 1.2.13:

• Xbios video driver disabled when FVDI present.
• Teamtap autodetection on joypad ports
  (Thanks to Fredifredo for teamtap and joypads).
• Xbios audio driver enabled for Magic
  (Thanks to Sascha Uhlig for testing).

Doom port Heretic port Hexen port

I tortured my head for hours, trying to find a bug I did not produce. In fact, the toolchain is faulty. Here are two elements that explain the problem.

20081213 Update: In fact, the problem came from my gcc 3.3 configuration. Using a newly built gcc 4.3.2 fixes the first problem. The second one is still valid though.

Multilib feature disabled in some cases
Incompatibility between FPU and non-FPU code

A new Aranym release is available. In the new stuff, many fixes for DSP56K emulation, mainly due to Laurent Sallafranque work, which works on Hatari, another emulator; and joypad emulation, so I can test programs that use it. I don't think I'll add Teamtap emulation till I need it.

I continued reverse engineering Resident Evil file formats , for my viewer Reevengi. I just found information to switch camera angle, given player position. I also started writing a software renderer, as there is no hardware OpenGL on Atari, to display some 3D objects on the background image.

Bugfix for LDG.
