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/...

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...

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 ...

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?

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 ...

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...

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...

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. Check this thread for how to write your own unlocked bios http://atariage.com/forums/topic/280673-removing-rsa-check-form-3do-bios-replacement-for-rom-chi...

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'...

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.

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.

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 ...

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.

Hi, Check over at assemblergames.com or obscuregamers.com. They are an active forum with many skilled modders. Put out a request for service and there should be someone near you who can mod your console. Their prices are reasonable but u may have to ship your console. I would suggest learning to sol...

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...

That's amazing work. Thank you for your efforts.

Thanks goldenband. It's a real shame that this place got blacklisted by Google, I only found it by accident because someone has linked a thread here on another forum. Is it not just a case of changing the site's server or domain ip or something. Hopefully Devin can work something out. This site need...

Hey man, thanks for the reply. Yeah I noticed the traffic on this site is unfortunately low. I'm also on AtariAge and Assembler focusing mainly on 3DO at the moment. Trying to work on feasible hardware solutions for this console both enhancing and restorative. Hopefully I will find some good info an...

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...
