MAME Info:

0.140u3 [Tom, gamerfan, Smitdogg, The Dumping Union]

HardDisk required


- 0.142u1: O. Galibert added some hardware information to the Midway Quicksilver driver.

- 0.140u3: Tom, gamerfan, Smitdogg and The Dumping Union added Offroad Thunder (Midway Games 2000).

- 8th December 2010: Smitdogg - I dumped the BIOS for Offroad Thunder.

- 24th November 2010: Smitdogg - gamerfan got us an Offroad Thunder computer. A copy of the hard drive was dumped previously but it can't be added to MAME correctly without a dump of the bios. Hardly anyone can dump it and I haven't even been able to get good info on the hardware until now (been asking around literally for years), so you should appreciate the pictures.

- 8th October 2010: Smitdogg - Tom has dumped the hard drive for Offroad Thunder and hopefully will get us the boot rom (or whatever it used, I've never seen high res pics of the motherboard) soon.

- 26th September 2010: t152 - I have a complete working Midway OffRoad Thunder box so I could help out with infos about that. Just let me know what you like to have dumped (drive, chips...). Smitdogg - Awesome, that will save us a boatload of cash. Can you get me high res pics of everything, boards, hard drive, if there is a dongle, if there is a BIOS bootup screen, the BIOS chip, go crazy on it. Then I could tell you for sure. At the very least, we need a CHD of the hard drive and a dump of the dumpable chips on the board (probably a BIOS + boot ROM or just a BIOS). And I know it might just look like a standard Award BIOS or something but we need the actual chip dumped if possible.

- 25th September 2010: Smitdogg - There are 3 possibilities of needed stuff at the moment so I want to see if anyone is interested in helping. Offroad Thunder, which is a great and old game and still somehow undumped. I'm researching an original set of it. It's extremely pricey but gamerfan might be covering most or all of it, I'll know more about that one in a few days. The main problem with these games and a lot like them is that they used hard drives and they have been failing and replacement drives are getting sold that work but are different sizes. Well, that's a best case scenario on replacement drives actually. Sometimes the data gets crap-hacked to let the hardware not use security dongles... Anyway the clock is ticking on them. And in fact we might end up accidentally buying a replacement drive on something at some point, forewarning. They're everywhere.
