Hi all! here's my GBZ WIP

[username 123]

I used two of these and they fit the battery compartment with no wasted space. Almost like it was meant for the gameboy.

looks good! just slightly shorter than an S3 battery but same width. nice capacity too! not sure how available they are in the UK though. I don't recognize that model name of phone

Just search for Samsung 2000mah battery online. I don't think they made more then one model of the 2000mah.

so...
Decisions... decisions.

I've been intending to use the adafruit 2.8" PiTFT in SPI mode for some time, but as many of you know, it's slow and lagsome...
I'd like to try and get it running in DPI mode though and get a great, lag free, pixel sharp display. but the downside is of course that it totally eats all the GPIO... which I wanted to use for controls, I2C, and the PWM audio but all of these are blitzed by putting the gpio into DPI mode.

so... do i go back to the drawing board and use a composite display, stick with the original SPI mode or lose all the functionality of GPIO and use USB sound and MCU HID controls...

also, using the display in DPI mode means saving a lot of space from nixing the display control board (and integrating anything i need on a new, custom PCB.)

bah

Is there a guide for getting it done in dpi mode on the pi??

[abrugsch]

Not for my screen but there are general guides, I just have to figure out how it pertains to my screen and its data sheet. But even in RGB565 mode it's most of the GPIO including the extra interfaces like pwm, spi, and i2c. Even using alternate pin mappings...

well since discussion on another thread has sort of forced my hand to reveal, my "something unique" is to be able to read real GB cartridges into the Pi.

I've been working on this for over a year but the whole project has gone stagnant since my 2nd son was born and I need to learn KiCAD to design a custom PCB for it.

anyway here's the video I made in April of the breadboarded reader hardware (2x MCP23017's and a DMG cart port)
(strange background noises are my local hackerspace. there's 3D printing nearby and circular sawing going on in the workshop!)

and the ROM dump in progress

it's fairly slow in that vid as it was before I did some optimizations to speed it up a bit, but even so, perfect dark is one of the biggest GBC cartridges going and it takes a fair while (255 data banks - tetris takes only 1!)

so thanks to [mention]que20[/mention] for outing me

ahah!
I'm sorry abrugsch, but congratulations for your son
I look forward to see your next steps!
