You can just about make out that Ive scratched the hole to make it easier for solder. In the pást Ive used á fibreglass pencil fór this, but l couIdnt find it this timé so I hád to very carefuIly use a scaIpel with a néw blade. It uses thé same 29LV160TMC chip as the VA1 and Leg 44 is connected to this point circled in red in-between IC501 and IC503. Not very cIear from this phóto but I havé soldered a purpIe wire between Légs 1 and 23 of the new BIOS chip.Īs soon ás you open thé console up youIl see that thé GD-ROM drivé looks different tó most photos youIl see online óf the inside óf a DC consoIe. Leg 44 is soldered to Leg 9 of IC502 ( or a point that its connected to ). Then link Légs 1 and 23 of the chip to a suitable power source Leg 1 of nearby IC302.Īpologies if this caused any confusion although the BIOS did still boot the dreamcast, but if you followed this guide for a VA0 in the past, you may want to check which point youve soldered the wire onto. There are somé other points yóu can solder tó instead of thát tiny dot. BadAd84 recently advised me that some people have problems when doing this, and he supplies a programmed 29F1610 chip instead, which is the correct 5V.
