Ok I did some tests using the hacked hkt0120 bios and the regions:
Bad news here, setting the region value to 00 does indeed change the swirl colour to blue and the region itself HOWEVER the region is NOT PAL, it is an unknown/unset region, thus no cd-r (JUE) will run with the region setting as 00. (it is probably a corrupted value) EVERY other settings appear to be japan. How so ? because the value at 0x126 is very likely not to be the only value to modify, to sum up, this value probably only correspond to ONE of the dip switches of the devkits. As you know there are several of those and some probably need to be set or unset at the same time as some others in order to change a region properly. Thus we need to find the other dip switch values to change. Yet the bios would still not be region free, so the best way is to hack it to bypass the region check in IP.bin
Finally the biggest problem will be to find a way to flash it into a retail dreamcast.
Also I noticed that the bios to be flashed in HKT-0120 units features a specific header and that this very header features a hash check, which would explain why it didn't work to flash it on the actual units. Do anyone know what errors were encountered when the owner of the devkit tried to flash the hacked bios ?
Has there been any progress regarding the dev bios? Sorry to drag out an old thread but I'm still curious of the outcome.
I assume to a degree it's fallen off the radar meaning no work/progress has come forth, however I always like to check.
