- 25th April 2004: Ville Linde fixed a few graphics problems in Viper Phase 1 and fixed a bug in the REP opcode so that it doesn't break the SPI games.

- 0.81u6: Ville Linde completely rewrote i386 REP/REPNE prefix handling. Fixes the following: Battle Balls attract mode runs correctly now, balls no longer all the same color in-game in Battle Balls, E-Jan now coins up and Viper Phase 1 is now playable (with encrypted gfx).
