WIP:
- 0.182: Replaced M68705 CPU3 with 'MC68705P5'.
- 0.180: Refactored LSA Squad priority prom usage [Angelo Salese].
- 0.138u3: hap changed clone Storming Party to a bootleg without MCU. Changed Z80 CPU2 and M68705 CPU3 clock speeds to 3MHz in Land Sea Air Squad.
- 0.136u4: Fabio Priuli added driver_data struct and save states to LSASquad driver.
- 28th July 2009: Mr. Do - Kiltron got busy this summer and recently cranked out Land Sea Air Squad artwork, on loan from Gene at Vintage Arcade.
- 0.131u1: Angelo Salese merged memory maps in the LSASquad driver.
- 0.128u4: Nicola Salmoria and David Haywood removed ROM banking kludges from Land Sea Air Squad.
- 0.122u6: Changed M68705 CPU2 clock speed to 4MHz.
- 0.115: Aaron Giles updated 68705 clocks to take into account the internal divide by 4. Added constant so that it is clear why this is being done. Changed M68705 CPU4 clock speed to 1MHz.
- 0.106u13: MASH added pld ($0 - pal16l8a.14) to Land Sea Air Squad and clone Storming Party.
- 0.84: Brian Troha improved dipswitches in LSA Squad. Added 'Difficulty' dipswitch.

- 0.37b13: InsideOutBoy fixed crashes in Land Sea Air Squad.
- 26th February 2001: InsideOutBoy fixed LSA Squad / Storming Party from crashing during the train stage.
- 0.37b5: Nicola Salmoria added 'Land Sea Air Squad / Riku Kai Kuu Saizensen' (Taito 1986) and clone 'Storming Party / Riku Kai Kuu Saizensen'. TODO: Unknown writes to YM2203 output ports (filters?). Wrong sprite/tilemap priority. Sprites can appear above and below the middle layer, it's not clear how this is selected since there are no free attribute bits. The priority seems to involve split transparency on the tilemap and also priority on sprites (so that people pass below doors but airplanes above). It is confirmed that priority is controlled by PROM a64-06.9 (grounding A9 makes sprites disappear). Scrollram not entirely understood - it's most likely wrong, but more than enough to run this particular game. The video driver is pretty slow and could be optimized using temporary bitmaps (or tilemaps), however I haven't done that because the video circuitry is not entirely understood and if other games are found running on this hardware, they might not like the optimizations.
- 13th July 2000: Nicola Salmoria sent in a driver for LSA Squad / Storming Party.
