    I am building a Dreamcast portable for the summer competition. My plan is to document most of the progress in a youtube video series. Here's episode 1


    I've already got the I2S audio amplifier working on the dreamcast as well as custom regulators measuring the power to around 7 watts not too bad. I'm also working on a dreamcast controller emulator (aka DC+). It seems I've got the basic controller functionality working, it's time to make a new test pcb for testing it in game with full controls. Next I need to study the VMU display and memory.

    The case will be modeled after the 2DS which I think is perfect since the Dreamcast has 2 screens.

    Been a while but I've been making good progress. The dreamcast controller emulator seems fully operational (besides VMU capabilities). I aught to make a new WIP video soon since I did promise..

    It is not so easy playing it on the table but you get the idea.. https://drive.google.com/open?id=1_Kmc5S5dYxoTdhebtDlzaSz5Gz2Uxj4D

    The controller pcb is based on a PIC32MZ (dreamcast controller emulator) which has 2 I2C slaves: LM49450 for digital audio, and a DAC for screen controls. Both are functioning. It also has 2 SPI devices: 128KB FRAM (memory card emulation), and .96" OLED display (VMU emulation and other features). I'm working on those two parts next. I admit my bit-banged maple bus receive code can only handle receiving one word at the moment. I need to figure out how to make it more flexible, but it is a difficult protocol -- I'm on it.
