Since I had to wait for the paint on my Pad64 to dry & the UPS man came by, I alredy started to work on my next portable 
This time it'll be a Dreamcast, here're the specs:
- Dreamcast VA1-Board + SD-Card + BIOS-Mod + VGA-Mod + G1-ATA (with 2,5" HDD).
- 7" Widescreen via VGA
- Frankencasing of the same case used for my N64p. It fit's the DC-Board just perfectly
- Batteries... 7.4v ~5000mAh... don't know exactly, yet
So first I set up VGA, there are some externel components needed for that, so I soldered them directly onto the board (It's quite nice to work with an "untrimmalble" board.. lot's of space
). After that worked out perfect, I added an SD-Card & test booted Dreamshell..
Next up was the Powersupply. I used a PTH08080 (2.25A) for 5V & one PTH08060 (6A) for 3.3v, since the DC requires a little over 2.2A on 3.3V.. Funfact: The 12V Gamecube power adapter is not capable of driving the whole DC via 12V. It will reboot randomly if something is wrong with the PSU. So I switched to a old ATX-PSU for supplying 12V to it... (12V is needed for the GD-ROM only).
So far, so nice! Next up was getting a second bios-chip onto the board & flash it with the custom Dreamshell-Bootloader with "no gd-rom" option. How nice I still have some of these EEPROMs lying around
And done! After that I removed the possibility to switch between the bios-chips, since I won't need the original one anyways...
So now my DC was ready for it's first run without the GD-ROM
Awesome! So next up was the G1-ATA cable... the "most difficult" mod on this board so far..
Sadly I couldn't test it now, since I'm still waiting for my 33.xxx MHz active crystals, that are required for the AICA-Chip on the board to work correctly.... But until now the DC is real joy to work with! lots of space, some nice alternative points & easy mods!
I'm still working out the alternative pins for the daughter-board (RTC, Controller, FAN-PWM Signal), which is required to boot, too. I'll most likely fake the PWM-Signal using a NE555-Timer, but i'll have a deeper look at the board first,... maybe there is a easier way of doing that..
Of course I'll release all my Pinouts if I've finished them
