[Craig Anstett, Andrew Welburn] (This new parent set runs on Epos's original Tristar 8000 hardware; the previously dumped set has been tagged as the Pac-Man conversion it is.) - Congrats to those that found original hardware version of the game and adding it to MAME source around Halloween timing too.....if that was being done intentionally that way. I predict the Eeekk! entry will get a new edit. https://mamedev.emulab.it/undumped/index.php?title=Eeekk! Runs on modified Pac-Man hardware (made by Epos)...the version credited to "Magic Electonics" (Magic Electronics) (probably just a copyright screen change) has not been dumped. There also may be one credited to Eagle Conversions. https://mamedev.emulab.it/undumped/index.php?title=Undumped#Eagle_Conversions_Inc I guess that now leaves having to find the "likely runs on Pac-Man hardware conversion" licensed to Magic Electronics version of this game.....and hopefully the game will then be considered fully "preserved". If only, former MAMEdev (Pac-Man hardware extraordinaire) dwidel were around since that hardware was his thing. https://mamedev.emulab.it/undumped/images/thumb/Eeek%21.jpg/250px-Eeek%21.jpg MrGoodwraith Barnacle Clinging to the Ship of MAME Reged: 10/12/05 Posts: 108 Send PM Re: more Eeekk! goodness [Re: gregf] #384145 - 11/01/19 04:17 PM Reply > If only, former MAMEdev (Pac-Man > hardware extraordinaire) dwidel were around since that > hardware was his thing. While I greatly appreciate all that Dave did for the project, I was disappointed that, despite my entreaties for a group bid, he and the other MAME-friendly devotees of rare games on Pac-Man hardware all competed against each other rather than pool their resources when a PCB of this type came up for auction back in ~2003. One of the Japanese collectors ended up winning that board and it vanished into the typical black hole. gregf Ramtek's Trivia promoter Reged: 09/21/03 Posts: 8611 Loc: southern CA, US Send PM Re: more Eeekk! goodness [Re: MrGoodwraith] #384148 - 11/01/19 11:26 PM Reply >> If only, former MAMEdev (Pac-Man hardware extraordinaire) dwidel were around since that >> hardware was his thing. >While I greatly appreciate all that Dave did for the project, I was disappointed that, >despite my entreaties for a group bid, he and the other MAME-friendly devotees of rare >games on Pac-Man hardware all competed against each other rather than pool their >resources when a PCB of this type came up for auction back in ~2003. I remember that thread on Gridle's old MAME.net web site. I don't remember exact year when that happened, but I figure you have that episode memorized in what year it took place since it was one of those of the 'ones that got away'. ;-) I was viewing that as a minor 'bump' in the road and the game would eventually be found, but I didn't expect it to be another 10 plus years going by before that game was eventually found and supported.

Basically each game's program code starts by reading the coin port and then locking up the CPU if bits 7 and 6 fail to match a constant value. This presumably is implemented by bridging the two corresponding input buffer pins to GND or Vcc; if so, it can be defeated with trivial wire mods.

I notice the driver was marked as imperfect colours? IIRC the colours on this are PROM based, are we sure it isn't just a bad PROM? gregf Ramtek's Trivia promoter Reged: 09/21/03 Posts: 8611 Loc: southern CA, US Send PM Re: more Eeekk! goodness [Re: Haze] #384189 - 11/06/19 09:26 AM Reply >I notice the driver was marked as imperfect colours? IIRC the colours on this are PROM >based, are we sure it isn't just a bad PROM? Assuming the fix is complete... - epos.cpp: Redumped color BPROM for Eeekk! correcting colors. [Andrew Welburn] https://github.com/mamedev/mame/commit/994fc674d6146201451d43d055f3e567fbd3122b - other stuff from the source src/mame/drivers/epos.cpp Epos Corporation IGMO and their other game Catapult still yet to be fixed, but hopefully respective pcbs and roms can be found and redumped in the future.
