Обновился эмулятор GB. Изменения:
- zBoy has been entirely rewritten in C language, using SDL for input, video and timing routines;
- Added support for 8x graphic scaling (which ends up with a game resolution of 1280x1152);
- Added support for screensaver inhibition under Windows (--NOSCREENSAVER);
- Palette customization has been hardcoded into zBoy (no support for external palette files anymore, but you can choose an alternative palette from a predefined set of palettes);
- Fixed the time adjustment routine (it doesn´t speeds up over 100% of normal game speed after being late for some time);
- Replaced the EPX graphic filter by Scale2x (slightly faster), and renamed EPX3 by Scale3x (which is the technically correct name);
- Made the Scale2x scaling the default one;
- Dropped DOS support;
- Dropped fullscreen support;
- Fixed the ADC opcode emulation (wasn´t setting the C flag when carry from bit 7) this made all the Megaman serie playable;
- Fixed the SBC opcode emulation (wasn´t setting the C and H flags properly);
- Implemented the gameboy type checking via the FF00h joypad register;
- Added the possibility to disable the graphic "Window" used in many games (by default under the F3 key);
- Fixed a bug in IRQ generated by the coincidence register
was generating several IRQs in one scanline (now it generates only one IRQ for a matching scanline);
- this made the intro of Prince of Persia working.
