0.37b7 [Nicola Salmoria]


- World Beach Volley sound is controlled by a pic16c57 whose ROM is missing for this game.


- Hardware: The games run on different, but similar, hardware. The sprite system is the same (almost - the tile size is different). Even if some games are from the same year, World Beach Volley is much more advanced - more colourful, and stores setting in an EEPROM. An interesting thing about this hardware is that the same gfx ROMs are used to generate both 8x8 and 16x16 tiles for different tilemaps. Hard Times and Hot Mind have different tilemaps layout than the other ones. Hard Times was hacked from Blood Bros. program code. Hot Mind is a romswap kit for Hard Times pcb, in fact it was found in a pcb marked as HARD TIMES 28-06-94.


- 0.94u4: Pierpaolo Prazzoli fixed some sprite colours in playmark.c.

- 0.94u2: Nicola Salmoria updated playmark.c. Fixed sprite/tile priorities in wbeachvl and excelsr. Found bitmap enable bit and added rowscroll support. Pierpaolo Prazzoli changed bitmap to be drawn after the fg_tilemap.

- 31st August 2000: Nicola Salmoria sent in a driver for World Beach Volley, again without sound due to an undumped PIC chip.

- 28th August 2000: Nicola Salmoria sent in a driver for Big Twin, without sound support though.
