Re: 3DO Time Warner CD not working

Does the ROM work on an emulator running a RSA hacked bios? Retail 3DO have an RSA check which won't allow games/ software without it to load. There is a way to replace the bios with an unlocked bios (http://atariage.com/forums/topic/280673-removing-rsa-check-form-3do-bios-replacement-for-rom-chips/...

Re: Dumping FZ-10 BIOS

Great work! I think IC680 is not used on newer FZ-10 with the ANVIL combined chip. Do you have any pics of the leakage around the IC. IC don't leak so this must be leakage from a near by capacitor. There may be trace damage. I would recap the motherboard and clean the residue before it causes any mo...

Re: Dumping FZ-10 BIOS

Good investigating. At least you know that 3DOA laser is dead and there is a fault on the motherboard as well. At this stage you will need an oscilloscope and the service manual to test further where the problem is. It may be a faulty capacitor on the main board or a faulty IC or the BIOS. At least ...

Re: Dumping FZ-10 BIOS

If your eeprom programmer is compatible with 29LV160, it should be compatible with 29F800.

That's really strange. I don't think the laser is strong enough to melt the plastic but the previous owner definately damaged it somehow. Have you tried swapping the laser assembly?

Re: Dumping FZ-10 BIOS

That pad is not connected to anything so it doesn't need lifting. I should have recommended MX29F800 instead of MX29LV160, my bad. The MX29F800 is a correct 5V flash rom. The MX29LV160 is a 3V flash rom. It will still work but its best practice not to use 3V signals in a 5V system. If you decide to ...

Re: Dumping FZ-10 BIOS

At least that rules out a bad PSU. Could still be a defective cap on motherboard but is more likely a defective CD drive. A 3DO USB mod replaces the CD drive and could be a solution. If you are still keen to read bios, check with the dumped bios online for similarities/ corruption. You can replace w...

Re: Dumping FZ-10 BIOS

The problem is that the BIOS is on a maskrom. It cannot be written to so it would need removing from the board anyway if you were looking to replace it. Therefore method 3 is the only viable option to successfully read and replace the bios. The Bios is most likely functioning normally. The spindle i...

Re: Dumping FZ-10 BIOS

Hi, the 3DO bios comes on either a 32 pin or 44 pin 5V maskrom. The Bios can be read using an eeprom reader/ writer set to read a 29LV160 eeprom.

Re: Possible replacement CDrom drive units for FZ-1 (new success

Thanks for the info. It would be interesting to know where he got the laser assembly from. The laser used is a Sf92.5. But there seems to be a couple of revisions. The short cable 11/4 pin seems to be a drop in replacement for the 3DO but the long cable 11/4 pin seems to have a different pinout. It'...

Re: Road Rash saying not enough memory to play music

All 3DO have the same spec. Check this thread with a similar issue https://assemblergames.com/threads/3do- ... ame.57265/

Could be a bad RAM chip. Check the electrolytic caps near the RAM chips as well and replace if faulty.

Re: Various 4DO problems

Are you using the libretro port of 4DO? https://github.com/libretro/4do-libretro

I don't think the original 4DO is supported anymore. If you still have issues, try Phoenix emulator.

Re: Introduce yourself.

I think there are a few people around coding small games. There's an interesting interview with 'Burger' Becky on how she ported Doom to the 3DO https://youtu.be/rBbIil2HPSU I read somewhere that some developers were trying to tidy it up and improve it for 3DO. There's another video on porting 'Out ...

Re: Introduce yourself.

Welcome back :) what's your area of interest? There's a few open source RGB mods in the works, a 3DO usb host is still around but the home brew scene is still vacant.

New 3DO RGB mod

So I've just finished designing a new 3DO RGB board using the BU3616K encoder. As the old mod boards were unavailable. This board will work on all 3DO revisions (except FZ-10 with the Anvil chip or Creative Labs 3DO blaster). Installation is similar to old mod with 24 RGB wires, SYNC, CLK, 5V and GN...

I haven't read the articles myself but it sounds like standard behaviour for the console industry at the time. 3do were looking to release the M2 around 1996/1997 but DVD tech in consoles was still a few years off, Ps2 released in 2000. 3do couldn't afford to wait that long in order to maintain a pr...

Hi, thanks for the add. Excited to be part of the dedicated 3DO forums. I recently became interested in the 3DO technology after reading about the 3DO Blaster. The more I looked into 3DO, the more obscure and alluring I found it. I managed to pick up an FZ-1 for a good price (£40) and promptly start...
