Does BIOS mod need bridge between R512 and 12v?

[darthcloud]

Hi,

I was wondering if the BIOS mod need the bridge between the R512 resistor and 12v like the region changer apps need.

I did the BIOS mod as show but it' doesn't work , DS intentify my flash chip correctly "DS_OK: Macronix flash detected, device id = c4"

Then it start erasing for a while, and after that. it try to write the first block and I got the following errors:
"DS_ERROR: Writing to flash timed out"
"DS_ERROR: Failed writing to flash at 00000001 (37 vs e3)"

My dreamcast don't have an 40pin TSOP flash like your, I have a 32pin TSOP (MB8581-70) instead but I connected the /WE line to pin 7 instead since it's the standard for flash of that size.

So I guess the problem is maybe the fact I don't have the R512 bridge.

If the bridge is not needed then I guess the problem is the /WE line..

Thanks
