2012.11.10 The Odalisque Dance Well, it seems obscure games coming from Italy are all the rage now, see Haze's blog on the recent Planet Probe success. Congratulations to all involved! Below you'll find some preliminary screenshots of Harem running in MAME. It's a 1983 arcade game by Italian I.G.R. There are several reasons why this game is interesting, none of them unfortunately has to do with its quality... First, it's a rather obscure production (prototype?) as only one PCB has ever surfaced since it was produced, and very little information can be found online. Second, it's one of the few original arcade games developed in Italy, and the only game ever produced by I.G.R., a company which sunk into oblivion soon after presenting its game that year at the ENADA exhibition (International Amusement & Gaming Machine) in Rimini, Italy. Third, it's been in MAME for 12 years as non-working, flagged as BAD_DUMP and encrypted, which surely scared devs off. And lastly there's the subject matter, a game set in a chlichéd Middle East where you have to chase women on camels, cars and tents and forcefully take them to the beds at the bottom of the screen... The hardware is yet another variation in the scramble.c driver. One of the program ROMs is bitswapped (easily dealt with), but still parts of it did not make sense code-wise. I figured out that's because opcodes and data are encrypted differently, and furthermore there are three different encryptions (6 bitswaps total) which can be selected at run-time though a serial register. http://www.lucaelia.com/images/mame_snaps/harem/0000.png http://www.lucaelia.com/images/mame_snaps/harem/0001.png http://www.lucaelia.com/images/mame_snaps/harem/0003.png http://www.lucaelia.com/images/mame_snaps/harem/0009.png http://www.lucaelia.com/images/mame_snaps/harem/0013.png http://www.lucaelia.com/images/mame_snaps/harem/0016.png I also shot a video of the game albeit colors are probably off, and speech from a Texas Instruments TMS5110 chip is missing (any takers?): https://www.youtube.com/watch?v=KfkFtTB66xU&feature=player_embedded Many thanks to Dave Hollister for preserving the game in 2000, and to hap( http://tsk-tsk.net/ ) for writing some notes on the encryption while identifying the hardware type, which caught my eye. ______________________________________________________________________________ 来源：http://www.lucaelia.com/mame.php/2012/The-Odalisque-Dance -- ポーラステーション http://perryt0517.wordpress.com/ --
