Hi everybody!
Here is Antonio from the '90!

The best game I ever played? I think it is FTA (Faery Tale Adventure) though I just used to kill everything moving to begin with. 
Later, once I started understanding a little bit of English, I could actually appreciate to the fullest the complexity of the storytelling!

What do I do now? Mostly program and design embedded electronics!
See you around! 

Hi there!

I would like to share with you a project I am part of!

As the title says, it is an open-source retro-game console that connects to VGA monitors.
I and a friend of mine worked on it and everything is fully Open-Source (HW and FW on https://github.com/next-hack/usvc)!
It has a very simple hardware it allows everyone to code and play his own 8-bit style retro games.
It is based on uChip (an open source Arduino Zero compatible development board, the size of a 16-DIP IC).

The console accepts standards USB gamepads and keyboards, and has a VGA output, with up to 256 on-screen colors. Games are stored in the microSD card, and are loaded into the MCU flash by the game loader.

We are running a campaign on Crowdsupply (www.crowdsupply.com/itaca-innovation/usvc) in order to spread the word and create a community that will help develop and improve this platform.

Here is a brief summary of its main features:

• Everything is handled by the 48 MHz Cortex M0+ microcontroller that powers uChip (an ATSAMD21), including VGA and audio signals, which are generated using carefully optimized ASM code. Games, instead, are programmed in C. All the code has been written using the free Atmel Studio 7.0 (using GCC as C compiler).
  
  


• There are for now three video modes, all working at 320 x 200 pixels. With minor modifications, you could achieve up to 320x240/400/480 pixel. Still 240/480 lines would leave too few time to the CPU (during the active video, the CPU is busy in generating the video signals). 400 and 480 vertical lines will have a pixel ratio 2:1.
  
  
• Since uChip has only one 10-bit DAC channel, the audio consists of four 30kSPS 8-bit PCM channels mixed down to a mono 10-bit channel.
  

Should I add something more? uSVC has 32kB of RAM a 256kB of flash (24k of which are used by uChip’s bootloader and game loader, the latter providing also shared USB and SD functions, so that you don’t have to include them in the games).
All the platform is running using only the 14 I/O uChip pins!

Fell free to give some feedback and suggestions for improvements!

I hope the wall of text didn't prevent you from reading till this point!

PS: Attached is the result we reached up to now with a few examples:
