I broke my other dreamcast please help

I think it's correct that you only need pin 1 (#RESET) and pin 44 (#WE) to be lifted as long as the chip is definitely pre-flashed.

Pin 1 can then be tied to VCC (3V3) pin 23, and pin 44 connected to pin 9 of the FlashROM.

@Gromber - What did you mean by "welded track"? Has a track or via lifted from the board? If so, which one?

You need to make sure that none of the pins are shorted to each other.
If you check with a multimeter, it's fairly easy to test between one pin and it's neighbour like this...

1+2...
2+3...
3+4... etc.

This must be done with the power OFF! (multimeter set to continuity / "diode" / "beep" setting).

Note that pins 32 and 33 will probably both be connected to ground, so they will test as shorted to each-other (this is normal).

Also, is that just flux across pins 3+4 of IC502 ("Flash")?

A very good tip is to use liquid flux when soldering...

I use a flux in a syringe. You can put quite a lot of flux across all the pins, then touch the soldering iron on each pin again.

The solder on the pins should flow very easily, just don't leave the iron on one pin for more than a few seconds (the flux will "boil off" after a while).

btw, let us know which pin / pad you think is broken. I could probably find an alternative solder point for you.
