Nebula 1.4

posted in Emulator Release by xip on May 19th, 2001

I assume we all know what this is. Here's what's new:
  • Some rom files has been renamed to match the latest CPS2MAME rom names.
  • Ability to filter the game list. You can select if you want to seel all games, or only the available ones.
  • Roms now aren't analyzed everytime Nebula starts. They are checked when romsets are changed or when you press the Rescan button in the OTHER config screen.
  • Changed main 68000 core to Bart Trzynadlowski's Genital 68k, which is a bit faster than starscream, and has less bugs (perhaps none).
  • Rewritten the layer 2 drawing code. Rowscrolling problems are almost fixed (only missing avsp intro). It has caused a small slowdown, but with the little speedup of the main core the speed should be the same as before.
  • 19xx gfx problems fixed at last. If you use old savegames, then the problems will not be fixed until a stage change in the game.
  • As some people has reported that the new gfx code (v1.3 and later) is slower than the older one (1.2 and before), then I've added the ability to use the old gfx code using the -oldgfx command line option.
  • Sprite priority code has back to the original code that causes less gfx problems.
  • Implemented sprite bankswitching (one of the still unemulated features of the cps2 hardware)
  • Added PNG unfiltering modes (Sub,Up,Avg,Paeth). PNG files created with other tools should look right now.
  • Fixed most Raster problems. Things look a lot better. Only remaining some sprite problems.
  • Changed the Savegame format. Now the sound is correctly restored when loading a savegame. The old format is still recognized and loaded.
  • Data files (configuration and savegames) are not encrypted anymore. If you want info about the format of these files, send me an E-mail.
  • Fixed the "controller setting forgetting" bug. It's fixed now, but it requieres that you delete the old config files.
  • Added the ability to save the controller data as the default mapping for games using the same button layout.
  • GUI graphics can be changed (see -packgui option and the section below). Get it at the multi arcade page.
