I took pictures of a lot of DC modems a while ago...
Im currently pre-planning on doing the switchable bios mod on my DC. i need a little help on what resistors to get on http://www.digikey.ca/. if you could help me that would be awesome :D
alright found a bunch of 10k resistor but they seem to be different wattages. I dont want to get the wrong wattage and fry my retail and dev bios chips

Sorry for asking so many question's but for the switch does it need to have a certain requirement. im thinking of something like this.

Yeah I'm new to this project. I've done alot of soldering projects in my day. i was 11 years old when i did my first ps1 mod-chip (fluked it lol). I'm gonna be buying all the tools i need for this project and future projects as well (Hakko Soldering Station FX-888, Soldering Tips, Solder 28 AWG 0.015, Flux pens, Soldering Wick, Kynar wire 30 AWG etc). I'm gonna be doing the Sega Saturn model 2 modchip to fit with a model 1 system for the second time as i failed the first time. As well with a region free bios and a GameCube mod-chip for region free/home-brew purposes. Thank you Bad_Ad84 i will be ordering soon. Thank you APE for letting me know the requirements for the switch.

Is it possible to upload the BIOS using dc-tool?
I installed the chip and the select seems to be working (one way, the original BIOS loads and the other, nothing happens because the new flash rom has nothing on it). I tried switching over to the new chip after dc-load-serial loads and using: "dc-tool.exe -u dc_bios.bin -a 0x0 -s 0x200000" to upload the BIOS. Dc-tool looks like it's sending the data, but when it finishes and I power cycle the Dreamcast, there's still nothing.

I'm hoping it's not the WE pin. It broke off and I had to remove some of the casing to get to it, but it should be connected.
Is there a stripped down version of Dreamshell that I could send over the serial upload? I'm really trying to avoid having to write to another CD.
At the bottom there is a smallish disc image. It would take some time to upload it using bog standard serial.
Just finished a BIOS and SD Card Reader Install
For those who might care, I've took the time to work on my non-working dual bios mod. I couldn't find the problem, so I removed every wires and resistor then reworked the pins soldering and put everything back. Yet it still didn't work! The problem was in fact the odd pin 9 of the flash chip, so I decided to solder directly to the pin rather than soldering to the via... And It Works!
Was a bit of a pain to solder on the flash chip, but in the end it has been the solution for me! (Used a smaller-ass solder tip though)
