I'm working on doing an internal DreamPi install using a Pi Zero W on my (US) Dreamcast. I've got a USB-GDROM in my Dreamcast, so my 12V rail is going unused. Does anybody know if I can just directly use that 12V for the LVI? I've seen other builds using a boost converter on one of the other rails instead, but if I can do it without that it would save me a few dollars and some space inside the console.
Also, on other internal builds I've also seen people using the 5V rail to power the Pi and the USB modem; has anybody experienced any issues with this? I can't find any info about how much current the Dreamcast PSU can supply, but I'm hoping a few hundred more milliamps on the 5V rail doesn't make a difference.
Thanks for any help.
