0.37b14 [Nicola Salmoria]


< Japan >


WIP:

- 0.164: Switched Hexion to configured banking [Osso].

- 0.161: System11 added clone Hexion (Asia ver AAA, bootleg). Note: This means there's an original AAA version out there, this one has been hacked to play the music on an extra M6295, although all the Konami custom sound code is still in there. Document chip locations and xtal based on Hexion pictures of Konami PCB and bootleg PCB [Lord Nightmare]. Fixed rom names.

- 0.153: Alex Jackson fixed severe right and up screen offset with overscroll in Hexion with flipscreen on.

- 0.144u7: Kanikani updated Hexion dipswitches. Removed 'Unknown' dipswitches.

- 0.142u4: Angelo Salese and O. Galibert implemented an almost complete Konami K053252 device emulation, adds accurate refresh rate timings and irq acks to Hexion. Removed deprecat.h usage in Hexion. Changed description to 'Hexion (Japan ver JAB)'.

- 0.131u1: MooglyGuy merged memory maps in Hexion.

- 0.130u3: Fabio Priuli improved Konami inputs, verified all 0x00 coinage effects which now use konamipt.h and fixed a few mistakes in Hexion.

- 0.59: Added proms ($0, 100, 200 - colors).

- 24th February 2002: Yasuhiro Ogawa added the correct color PROM to the Hexion driver.

- 0.37b15: Changed Konami 051649 clock speed to 1.5MHz.

- 12th April 2001: Eisuke Watanabe fixed Hexion sound.

- 0.37b14: Nicola Salmoria added 'Hexion (Japan)' (Konami 1992). TODO: There are probably palette PROMs missing. Palette data doesn't seem to be written anywhere in RAM. The board has a 052591, which is used for protection in Thunder Cross and S.P.Y. IN this game, however, it doesn't seem to do much, except maybe clear the screen. During startup, some garbage is written to video RAM. This is probably supposed to go somewhere else, maybe the 052591. It doesn't look like palette data.

- 13th March 2001: Nicola Salmoria added sound emulation to Hexion, but colors are still missing.

- 12th March 2001: Nicola Salmoria sent in a preliminary driver for Hexion, but it lacks correct colors and sound at the moment.
