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 😁

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!

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)

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 ❤️

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 🤔

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 👌

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!!
