0.122u8 [Phil Bennett]

0.96 [Phil Bennett]


Bugs:

- lockon, lockonc: Bookkeeping says Credits A, B & C have a credit in it but i did not actually did so. scoobydude51 (ID 05374)


WIP:

- 0.145u8: Phil Bennett fixed missing sprites/HUD regression in Lock-On.

- 0.136u4: Fabio Priuli added driver_data struct and save states to Lock-On.

- 0.122u8: Phil Bennett fixed Lock-On - Game now playable. Added Lock-On (rev. E). Significant improvements to the driver. Added POLL input handling to the NEC V20/V30 core. Added 6x Volume Filter sound. Changed VSync to 55.803571 Hz. Added 'Coin A/B', 'Enable H/W Tests Menu' and 'Unused' dipswitches. Renamed (lockon) to (lockonc). Changed 'Lock-On' to clone 'Lock-On (rev. C)'.

- 27th January 2008: Phil Bennett - Lock-On: Now with accurate sprite-scaling and frame-buffer rotation.

- 0.118u3: Changed NEC V30 CPU core to use a 16-bit data bus [Aaron Giles, Phil Bennett, Pierpaolo Prazzoli]. Atari Ace added new AM_READ_PORT() macro which lets you define an input port read callback based on a port tag. This is now preferred over the previous technique of calling port_tag_to_handler() within an AM_READ() macro. Updated Lock-On that uses the latter pattern to the new system.

- 27th June 2005: Phil Bennett - Contrary to the main CPU ROM tests, the ROM loading was incorrect. Shuffling them around results in sensible behaviour. I still need to correct sprite co-ordinates before it can be classed as playable. Also, by loading the entire sound ROM sound is greatly improved.

- 21st June 2005: Phil Bennett - Added preliminary ground drawing to Lock-On (has lack of perspective). The sprites are still all over the shop as I haven't figured out how the X and Y co-ordinates work.

- 0.96: Phil Bennett added Lock-On (Tatsumi 1986).
