Sega Dreamcast Region Free BIOSA while back, link. Dreamcast BIOS. Not only did he make it regionfree, he also inserted the 3. D bootup animation from the Dreamcast Development Unit BIOS. Have a look at the startup animation which has been hacked into the BIOS, its from a DC Dev machines and looks great Thank you to the people over at Retro. Mods, I saw this new regionfree DC BIOS, which removes the VGA check along with some other features. Heres the developers site, the BIOS is still being developed too Why perform this mod Well youll end up with a Dreamcast which is different to most others, plus it will be truly region free, the current 4 wire modchips need you to switch the console off and back on again if swapping between different region discs. This one skips ALL region checking. There are a couple of different ways to fit this BIOS. Complete BIOS Replacment. You can remove the existing BIOS chip, and replace it with a pre programmed chip looking for a cheap reliable source for this chip, Ive bought some from BadAd. Obscure Gamers, he even offers a flashing service Once you have the programmed chip, then you can simply remove the old BIOS and fit the new one, you still need to lift and solder leg 4. This is the VA0 motherboard, you need to lift Legs 1 and 2. IC3. 02. Leg 4. IC5. This is the BIOS fitted to a VA1 more common motherboard. Leg 1 is lifted and soldered to Leg 2. NOT lifted. Leg 4. IC5. 02 or, at least, a point that its connected to. Ignore the two wires which are soldered to the legs of IC5. Piggyback BIOS Install. Start by lifting leg 1. I gently heat the leg where it joins the motherboard and then with a scalpel or needle I lever it up, and carefully straighten it with a pair of needle nose pliers. Then start on the Flash Chip 2. LV1. 60. TMC 9. 0. We need to start with straightening the chip legs. News, reviews, previews, tips, and downloads for multiple platforms.

MIO-Console-5.6.07.219-Free.jpg' alt='T-Link Console Software' title='T-Link Console Software' />Then we need to bend them again, this time they should just have one bend in them. Hold the chip vertically so all the legs are pressed against a flat surface. Then push the chip so that all legs are bent at a 9. Then test fit the new chip onto the existing chip. The legs will probably be a bit too short, but thats okay, we can still solder them together. Remove the new chip, and now prepare the existing chip. I was worried about adding too much solder to the BIOS chips legs and joining two or more together. So decided to work my way around with a continuity meter and discovered that legs 3. When I finished preparing the legs, I did the same check. We want to add a small amount of solder onto each leg, once you pickup the technique for this it wont take too long. I hold the tip of my soldering iron on the very top of the leg on the red dot in the photo, it heats the leg up, be ready to immediately add a small amount of solder to the leg, it should quickly take to the leg and cover it. The photo below shows Ive done legs on the left hand side. You need to now straighten some legs on the new BIOS chip as we dont want these soldered to the old chip legs. Gently bend legs 1, 1. VA0 motherboard. Now I place the new chip on top of the old one, and dragged the solder up from the old leg onto the new leg. Recently Run Programs Registry here. The photo below shows Ive done the first few legs on the right of the photo, the red dot is where I place the soldering iron tip, and then drag the iron up onto the new legs, taking some solder with it. Work your way around and do this to every leg. Dont worry too much if you dont join the legs up first time. The photo below shows a couple of legs that didnt join up, this is easily fixed though. It could be that the legs on the new flash chip have been bent too much, and you need to pull them out a bit so that they are level with the old chip legs, then try the same technique of dragging the solder from the old leg to the new leg. If that doesnt work, then we can add a piece of wire, this is Kynar wire, Ive stripped a length of exposing a couple of centimetres of bare wire. You can use any fine wire really, I just have a large reel of this stuff as its handy. Hold the wire in place, heat up the solder on the old chip leg Number 1 below, then heat up the solder that you had previously dragged up onto the new chips legs Number 2, then trim the wire. Repeat this on all the legs that need it remember, if youre doing this to a VA0 board, then Leg 2. Now, you can test your soldering again. Check each leg with a continuity tester and make sure that it confirms that the old and new leg are soldered together. If you think youve put too much solder on a leg and joined to adjacent legs, then you could test this also remember that legs 3. Lets start with the most awkward wire to solder now. The leg of the flash chip needs to be linked to pin 9 of the adjacent chip just behind it assuming VA1 motherboard, on the VA0 motherboard its leg 7. Look how small those legs are You should be able to see that the leg is linked up to a small hole on the motherboard, I gently scraped the coating from that hole you can see that in the first photo above, and then melted a small bit of solder onto the point. You can see the short piece of Kynar wire that Ive used to link leg 4. T-Link Console Software' title='T-Link Console Software' />If you dont fancy trying to solder to that small point, there are some alternatives. Now grab your 1. 0k resistors, you can see how Ive bent and soldered the first one to the joined up legs 2. BIOS chip. The second resistor was cut and bent to fit between legs 1 and 1. Flash chip. Once the resistors are in place, solder a final wire inbetween leg 1 of the new chip theres already a resistor soldered to it remember, to the linked up legs 2. Thats the green wire in the photo above. If youre doing this to a VA0 board, then Leg 2. Now its time to solder the switch in place, this lets you select between the original BIOS and the new BIOS. I hope the numbered photos above explain what to solder to each leg etc. Middle contact of the switch to the single point of D5. Its ready to re assemble now. I decided to insulate the metal plate directly above the new BIOS chip just in case one of the resistors move and touches it my resistor legs are too long really, later on photographed a different install where I shortened the legs a bit so that there was no risk of them bending. You can re assemble the console but leave all the screws out and the top of the case off, you can then use the switch and hold the lid control switch also. Switch your machine on and if you get a blank screen then youve probably got the switch in the position which selects the new currently blank BIOS. Flick the switch and restart the console. It should start up now as expected, set the date and time thats because you had to remove the controller ports with the battery on. Download and burn the link. Nero Burning ROM disc image. I burn it at 4 speed Disk At Once mode. Pop the disc on, hold or tape the lid control switch and either restart the console or select Play from the dashboard. This disc is a customised version of DC Swat Dream. Shell disc, Ive altered the configuration files and deleted the alternative BIOS files to try and make the download as small as possible.
