- There's a black bar on top of the in-game screen. It's most surely not created by maintaining correct aspect ratio. Iaspis (ID 00144)


- 12th November 2008: David Haywood - I've spent the last day looking at some Kaneko titles. I asked Andreas to take a look at the MCU data rom for several of the games, to see if it could help improve the protection simulation in Blood Warriors (by finding the tables we're using in the encrypted data rom, thus no longer requiring extra tables). He reported back to me with his findings, and it was good news. While this still isn't true emulation of the MCU it helps, as we know the tables in the MCU data rom are correct, while the ones figured out via trojans could potentially have had inaccuracies in them (they didn't... but). As a slightly surprising bonus all the 'Toybox' data roms apart from GTMR2 use the same main encryption, and same communication method. Bonk's Adventure is a bit odd (seems to use data not present in the MCU data rom) but was already figured out.

- 0.123u4: Changed the 2x OKI6295 clock speeds to 2MHz.

- 0.112u2: Guru and Sebastien Volpe improved Bonk's Adventure: Protection data fully verified, this corrects tilemap colors in levels 2 and 3. Fixed implementation of MCU command 43.

- 0.89u5: Sebastien Volpe corrected Bonk's Adventure priorities (according Luca's scheme), sound 'improvements' (both banking and rom loading), game name updated, interrupts scheduling change (not correct, but somewhat improved, see comment) and as a consequence, fake region dsw is removed. Swapped sound2 roms ($0, 200000). Changed description to 'B.C. Kid / Bonk's Adventure / Kyukyoku!! PC Genjin'.

- 0.88u2: Sebastien Volpe fixed Bonk's Adventure - Game now playable. Some gfx/sound issues. Fixed gfx1/2/3 roms length and sound 1/2 addresses. Added dipswitches 'Ticket dispenser' and 'Region'.

- 0.87: Sebastien Volpe fixed dipswitches in Bonk's Adventure. Changed description to 'Bonk's Adventure'. Added dipswitches 'Free Play', 'Demo Sounds', 'Title Level Display' and 3x 'Reserved'.

- 0.83: Added EEPROM and dipswitches 'Difficulty', 'Join During Game' and 'Allow Continue'.

- 31st May 2004: Tomasz Slanina added the EEPROM to Bonk's Adventure, but the game still isn't playable because of protection.

- 7th May 2004: Tomasz Slanina - Bonk's Adventure is not playable (protection isn't emulated, dump is incomplete).

- 0.77u2: Added gfx3 rom ($0 - 2MB scrambled tiles).

- 0.77: Pierpaolo Prazzoli added Bonks Adventure (Kaneko 1994).

- 9th November 2003: Pierpaolo Prazzoli added Bonk's Adventure to the Kaneko16 driver, but it doesn't work because the MCU isn't emulated.

- 20th July 2003: Guru - Received Bonk's Adventure (Kaneko 1994). Big thanks to Leonid81, Bob Schultz, jmurjr, Smitdogg, f205v, Kevin Eshbach and many MAMEWorld contributors.
