First steps in a new project starts working, yay 😊
#MegaDuck Super Junior Computer gets reversed! I invested several hours to pull "proper" schematics out of the PCBs and shared them on GitHub.
During the process I also completely redrew the MainBaord PCB surrounding the CPU.
The PicoDVI-N64 has audio support. But right now first thing to figure out is, what is wrong with my tool chain 😅 cause regardless of what I did, I just got "no signal". @zwenergy.bsky.social pointed out I should try the uf2 from the release page which finally produced a picture.
Finally! External #MegaDuck Laptop HDMI based on #PicoDVI is working.
This is pulled directly from @remysharp.com pico-dmg-arcade as I'm currently unable to compile working code myself. Need to figure out how, to add audio support though 😁
The nileswan cartridge
I've spent the last two years developing firmware and software for a WS/WSC/PCv2 flash/development cartridge. Now, it has finally been announced and will be sold by 49bitcat in Germany. Sales start November 24th!

An open Playstation 1 SCPH-5xx1 model with the PU-18 revision motherboard. There is a custom ROM chip soldered in to replace the BIOS and an open source optical drive replacement installed as well.
I have concluded my open source experiments with the PlayStation 1! I wanted to see if I could remove the region lock, install an open source disk drive replacement, and make it all work with a libre BIOS. Good news: you can!

My IPS mod for the #MegaDuck Super Junior Computer finally got a frame to hold the GBP Q5 display.
It also locks against the adapter PCB and creates a good tight fit ^^
Now I need to find a nice way to access the OSD without the capacitive-pads (inconvenient)
Hau mal lieber endlich den STE an xD
This huge "romhack" definitely deserved a physical copy 😁
Took a Conkers BfD Repro, added an UltraCIC-III 6103 so it runs on PAL as well as NTSC. Can't wait to have time to play it ❤️
Its a real pain that the Blue sky handles are this long... It reserves to much space to Tag a single person...
Wanted to tag @bbbbbr.bsky.social as well 😁
We just got a #MegaDuck printer! It's in very good condition and working just fine 👌
Therefore we can now properly trace the printer protocol, reverse it and make printing accessible for everyone 😁
Even though we then still need to figure out how to enter the 4-color mode 🤔
@zwenergy.bsky.social
Latest Board analysis uncovered, the #MegaDuck Laptop has a Display interface on the back.
Hooked up a TangNano4k to it and got HDMI output 👌
Modless HDMI for MegaDuck Laptop incoming, I guess 😁
My German #MegaDuck Super Junior Computer looks pretty spanish right now 🤔
Might be because I swapped the SysRom with a freshly programmed AM29F040 flash ^^
thanks to @bbbbbr.bsky.social who gave me a dump to test 👌
Need to add it's the first discrete flashcart with SRAM support. The picoDuck by @zwenergy.bsky.social has SRAM support, as well ^^
Today my 4Mbit flashes arrived.
I immediately tested them and what should I say? Success!
The first ever to exist #MegaDuck FlashCart supporting SRAM saves 👌
This is now a standalone DataBank Module with embedded memory.
Neat 😁
#MegaDuck SJC #IPS board rev2:
Realigned the FFC-Connector and added a JST-Connector for Battery Feed.
The IDC was 1<->2 swapped. Fixed 👌
Pretty much the final version.
OSD Controller next 😅
#MegaDuck Flash+FRAM Cart Work log:
Part 1: FRAM
Check 👌
At first the flash cart caused the system to crash completely... I therefore analyzed the memory module port to find out I missed one trace... CS for FRAM is generated via A14 and CS... I only found the A14 connection first 😅
First iteration of my #MegaDuck Flash+FRAM Cart.
Unfortunately I forgot to order the proper flash (4Mbit) but that's okay.
Should support all known mappers as well as SRAM saves.
Stay Tuned 👌
Big thanks to @bbbbbr.bsky.social and @zwenergy.bsky.social for help, analysis and inspiration ❤️
I proudly present the (to my knowledge) first and only IPS Modded #MegaDuck Super Junior Computer 😁
I designed a special PCB to connect to a GBP Display from AE.
V2 in the making 😅
The Voice-Chip of my #MegaDuck Laptop has a broken trace under the Blob... therefore i needed to come up with a replacement.
RP2040 FTW! This uses "pico-pwm-audio" by @robingrosset with a few changes to cycle through the 6 files.
Now only the CMD-IF is left 👍
Want to replace my MegaDuck Laptops Display with an RIPS Q5. In order to achieve this I first successfully attached a DMG Display I had lying around 👌
#MegaDuck #CougarBoy
Designed my own version of #PicoNES
Wanted a PicoNES as close as possible to the NES ^^
Supports #BlueRetro incl. Controller detection as well as (probably) remote Power-ON (still to be tested).
Final Version will also replace the µSD Module and with µSD-Slot.
Today was pre-christmas 😍 I got a lot of toys (and duties 😅) from Consoles4You . I believe I SpyderMS (codename for ViperMS programmer🤪) my old gbaHD-US will get a new shell as well 😍 finally: no longer missing the "D" 😉
Thanks to my recent haul from Aliexpress, I was able to secure a replacement Spartan board. After programming the latest firmware on it, I installed it into my GBAHD and IT LIVES!!
