A20 / Re: Unknown variant of A20
Last post by Daniesrlow - Today at 03:08:07 AMWow, that's quite a find! Finding an A20-OLinuXino-LIME2 in a dumpster is pretty wild. Sounds like a fun project, though definitely a challenging one with all those missing components. It's like you're trying to rebuild something after a major event, a bit like causing chaos in Solar Smash! Seriously though, powering it up without those connectors sounds risky. Maybe start with the USB OTG and see if you get any signs of life? Good luck, and keep us updated!

Last post by Daniesrlow - January 07, 2026, 07:11:14 AMHey, I've tinkered with similar camera setups before! It's frustrating when i2cdetect doesn't pick anything up. Double-check your ribbon cable seating – those connections can be finicky. If the physical connection seems solid, maybe explore different device tree overlays for your Pi?

FPGA / toolchain for GateMateA1-EVB
Last post by mastupristi - January 04, 2026, 06:12:38 PMHello,
The document ug1002 "Toolchain Installation User Guide" is listed on your website.
Inside I find:
Following the directions, however, I find this:
https://colognechip.com/programmable-logic/gatemate/toolchain/
It seems that document ug1002 describes the legacy toolchain called cc-toolchain-linux.tar.gz,
but as you can see on the page, the most recent toolchain is oss-cad-suite-linux.
However, I cannot find any usable examples in this new toolchain.
I found some examples (perhaps) that could be useful here: https://github.com/YosysHQ/prjpeppercorn-test-cases
What do you think about using the new toolchain?
Do you have any quick guides on this? Or even just suggestions?
regards
Max

FPGA / Re: Questions about GateMateA1...
Last post by mastupristi - January 04, 2026, 05:40:57 PMHi,
I found this: https://youtu.be/lMUQplZXPoM?si=BMzlcv0eBE_oDg0y
Where they referred to the 'blink' example.
It is present in the toolchain, but it needs to be edited to change the pin definition, which is set to CCGM1A1-E1 by default.
I searched on GitHub and found a couple of repositories that contain the blink example with the pin definition for Olimex:
I hope this helps others.
regards
QuoteNo idea. Some bit file was provided by Cologne community if I remember correct. The software usage is detailed here: https://github.com/OLIMEX/GateMateA1-EVB/blob/main/SOFTWARE/ug1002-toolchain-install-latest.pdf

Neo6502 / Re: Creating ARCADE games for ...
Last post by Maarten van Druten - December 24, 2025, 06:02:09 PMWhile trying to build the game I found out problems,
The makefile uses ca65 (cc65 assembler) but the source code was written in 64tass syntax!
So I am fixing this now and will upload the right files on github soon

Last post by Maarten van Druten - December 23, 2025, 08:31:26 AMI posted my files on GitHub:
https://github.com/MishaOpenArcadeSystem/Gaudens-Machina-EX
Who can help me to accomplish following goals:
1 - Make this game work on Olimex NEO6502
2 - If the game works create a manual how to configure the Olimex NEO6502
so it boots automatically into the game when turned on

Last post by Maarten van Druten - December 23, 2025, 08:05:19 AMThe "Gaudens Machina Ex" is the most complete game
COMPLETE "GAUDENS MACHINA EX" ARCADE GAME FEATURES:
✅ 8 Full Zones with unique gimmicks and aesthetics
✅ 9 Sin Archon Bosses with multi-phase battles
✅ 32 Achievements with cute badge graphics
✅ 10 Weapons in the Temptation Arsenal
✅ Deep House Music Engine with 6 channels
✅ Sensual Particle System with heart/ribbon effects
✅ Battery Save System with 3 slots
✅ Cheat Codes & Easter Eggs
✅ Endless Mode with procedural generation
✅ True Ending with multiple requirements
✅ Enhanced UI with ecstasy meter and badges
✅ Mirror World gimmick mechanics
✅ Heartbeat Rhythm gameplay
✅ Weapon Evolution system
✅ Replay System with compression
Total Size: ~48KB (6 banks of 8KB each)
Estimated Development Time: 3-6 months for a skilled 65C02 developer
This complete system pushes the Neo6502 to its absolute limits while delivering a deep, sensual, and rewarding shoot 'em up experience that stays true to both arcade roots and modern design sensibilities! 🎮✨
Game structure:

Goals I would like accomplish:
- Bring new life in the Open Arcade scene by sharing code, games
encourage other game makers to make real 8bit Arcade games!
- When the Arcade games are finished, I would like to make real wooden Arcade cabinets
(like Barcade) for each game, and share building plans, etc.
- Boost sales and popularity for Olimex :-)

Neo6502 / Creating ARCADE games for NEO6...
Last post by Maarten van Druten - December 22, 2025, 08:52:44 PMHi my name is Maarten, with the help of Deepseek I created two arcade games for the NEO5602 that will push this hardware to the max.
One is horizontal shoot 'm up called "Gaudens Machina EX"
The other a vertical shoot 'm up called "Candy Monsters XXX"
both games have huge sprites, big end bosses, sound and even easter eggs
I have 90-100% of the assembly code ready, but I am a game art director, graphic artist not a programmer, I am looking for a person who can combine these assembly codes into a working game, who want to join me to release these two arcade games for the Olimex NEO6502 under the GPL3 license?
