0.99u2 [Tomasz Slanina]


WIP:

- 0.173: Cleaned up and identified I/O chip as 6821 PIA [Dirk Best]. Fixed maincpu rom loading. Changed description to 'Attack UFO'.

- 0.150: Curt Coder fixed MOS6560 warning (if (m_tone1samples == 0)).

- 0.148u5: hap fixed missing MOS656X sound in Attack Ufo.

- 0.147: Refactored MOS6560 interface to use DEVCB. Refactored VIC to a modern device (sound\mos6560.c). Refactored to use an RGB32 bitmap [Curt Coder]. Removed not needed includes [Miodrag Milanovic]. Replaced 'MOS 6560 / 6561 VIC' sound with MOS656X (1022727 Hz).

- 0.136u4: Fabio Priuli imported MOS6560 device emulation from MESS for Attack Ufo and removed the existent custom audio/video emulation. Added also driver_data struct and save states to Attack Ufo. Replaced 'Attack Ufo Custom' sound with 'MOS 6560 / 6561 VIC'.

- 0.134u3: Stephane Humbert fixed dipswitches for Attack Ufo. Replaced 'Unknown' dipswitches with 'Bonus Life' and 'Unused'.

- 0.129u4: Changed 'Custom' sound to 'Attack Ufo Custom'.

- 0.116u1: Changed palettesize to 16 colors.

- 0.116: Changed palettesize from 16 to 5 colors.

- 0.112u4: Cleaned up attckufo driver, making it perform like a 1MHz 6502 game once again [Aaron Giles].

- 0.99u2: Tomasz Slanina added 'Attack Ufo' (Ryoto Electric Co. 1980).

- 15th August 2005: Tomasz Slanina - Game is running on VIC6560 - like chip MOS6560, with few changes in the internal structure. Video, colors and sounds are emulated now (based on PeT's 6560 code from MESS).

- 7th August 2005: Tomasz Slanina - Weird (and probably rare) invaders clone from 1980. The main CPU is a 6502. Gfx is tilebased (128 dynamic tiles in RAM + 128 static in ROM). Screen size is strange - 176x184 (22x23 8*8 tiles). Colors are unknown. Sound hw is unknown too, possible discrete.
