gdrom board out of order :(

[somacast]

hello,

during my early attempts to do the mod I had sone wiring errors so I had to solder & desolder maaaaaany times, so I ended up with a gdrom not working when i fix it, i tried cleaning etc didnt help, it behaves as if no gdrom is attached (black screen then still dreamcast logo).

story goes on, as i by mistake removed (R233), i just tried to fix it without magnifier lens so i fixed it wrong in short circuit, so when i tried the board smoke smell came quickly and i did not try it again,

is this repairable? i dont have the R233 it was broken,, so where to start, because like this my stock dreamcast is not working
