This thread will be a technical deep dive into my journey to trim the Sega Dreamcast even further beyond. I’ve been working on this project for over 5 years, mostly in private. It's been very challenging, and a huge learning experience for me. The many lessons I've learned from Dreamcast trim...

My gift arrived today! I got some delicious toffee and a beautiful pink candle! Is the candle homemade? The wooden wick makes me think so. Smells awesome, like rosewater. Yum, even more homebaked goodies! The last thing in the box made me absolutely giddy! A stained wood Dread Suit Samus...

Joycon sticks and Vita sticks output analog X and Y signals just like any other joystick. You can connect them directly to the controller, and they'll function, but the deadzones and sensitivity may not be great due to the sticks' different construction and output voltage ranges. Vita 2000...

Hell yeah, I'm so glad someone finally did it! :awesome:

The Hollywood-2 Kawaii is alive! I'll let the pics do the talking. Final dock revision (for real this time!) Thermals are already way, WAY better than before. More testing to come after Thanksgiving!

I'm working on a Hollywood-2 OMEGA for Kawaii and made these quick diagrams for USB + GC controllers. Sharing them here for posterity!

.020" solder is great for portablizing-type stuff. Besides SAC305 and SN100C, maybe consider Kester 275 K100LD? In terms of flux, these are all good options the community likes: Chipquik SMD291 and SMD491 MG Chemicals 8341 Amtech NC-559-v2-TF (or Stirri V3-TF) When I need liquid low-solids...

Today I conducted some SNES Jr. undervolting and power measurement tests. Amazingly, the 1Chip system can run from 4V and even 3.8V with no issues besides reduced video levels! Here are the results. This is total SNES power consumption, including the cartridge, a controller, and Scampi in...

Well, first off I'd swap that Kynar for some 34AWG magnet wire: Did you hot air the AVE onto the flex after tinning the GND pad? If the AVE's exposed pad isn't soldered to the FPC, the AVE will misbehave. Also, some of the AVE legs on the left side don't look well-soldered. Nudge each one...

Well, I'm making slow but steady progress on the mainboard. I cleaned up the SNES core schematic, which was a disgusting EAGLE mess before because I didn't know what I was doing. The Super Everdrive schematic is done, and the routing is in progress. What I'm dreading is the cartridge...

Oof, document scanners aren't ideal for this. Definitely try to find a photo scanner if you can! Self-service office places are a good place to look. If you can't find one locally, Epson brand scanners (4800+ DPI) can be had on eBay for ~$50. Redherring32 and Lazr got on the Epson train and can...

Good stuff! What DPI will you be scanning at? I find 2400DPI TIFF ideal for boards of this density.

The calibration is really robust and works with just about any stick, assuming it's not mechanically faulty or wired incorrectly. Confirm the stick is powered from 3.3v, and its GND is connected directly to the Pico. Measure the X and Y axes to confirm they are idling at ~1.65V and the voltage...

Hey, welcome! The 2DS has one big screen inside-- there aren't two separate LCDs like in the DS/3DS. So, you wouldn't be able to use the original screen. The motherboard is also really big and has high-speed stuff spanning the top and bottom halves. Unfortunately, a conversion would be...

The U10 performs "power-on reset" by keeping the Hollywood's hardware reset pin low until the 3.3V rail rises above 2900mV. The reset pin is pulled up inside the GPU, so without U10 connected to hold it low, the Hollywood comes out of reset at some undetermined & unsynchronized time, based on...

Congrats to everybody who participated!

MCAD is getting very close to completion! Just need to wrap up the cartridge slot mounting and ribbon slot, and then I can lock in connector placement and start on the mainboard routing.

Pretty much. The Everdrive and cart slot will both be connected to the cartridge bus via autodirectional level shifters. The housekeeping MCU will toggle the OE pins of the shifters to "activate" one or the other. With the Everdrive not populated, the switch will effectively disable the cart...

Got some CFW-able CECH-2501s! The JTP motherboard is huge but it will be a good testbed for CFW and syscon shenanigans. After installing Evilnat 4.89.3 Cobra 8.4 [PEX] [CEX] [noBD+noBT] I removed the disc drive controller and the Wi-Fi/BT module. It still loads games! Great to confirm that...
