ZX-Uno is a FPGA computer like Raspberry Pi but not for Linux or Android.
It implements 8-bit computers hardware like OneChipMSX and MiST!
Can have 9 cores flashed at the same time, to choose one from the menu to start!
Have cores for ZX48/128, Acorn BBC/Electron/Atom, AppleII, Atari800/XL/2600, VIC-20, ORIC, Sam Coupe, Sega MS, NES, Colecovision, Jupiter ACE and now MSX1 with SCC and RAM mapper!
Will follow soon ZX80/81, C64/PET and Amstrad CPC (if any expert will help).
MSX1 core is still at beta stage. Maybe someone can help to polish the MSX1 core or maybe help for CPC core or create a new MSX2 core!

Raspberry pi doesnt contain FPGA, its an ARM-based computer.

but anyway, great news! I love the small size of the device Big smile

Yes, you have right, I wasn't clear. I mean Raspberry Pi size board which contain FPGA like MiST and OCM.
I put it in a RPi case with some minor modifications.
Everyone can have one for 70 euro shipped at Europe! The ZX-Uno team located at Spain.
Ask Antonio Villena at forum for availability. I took it from him.
Cool

Hi,

Yes, I'm the creator of the core!

It's a simple MSX1 core, with 128K of mapper, 256K of Megaram SCC (from OCM code) and Nextor with SD Driver.

Some people are reporting some bugs, I need to analyze.

Great job Fabio !
Hope this design could be ported to chinese EP2C5 board like Coleco Wink

how load nemesis/nemesis 2 in this core?
romload??, mgload?...
the memmory is:
128kb RAM
128kb RAM(as ROM)
256kb megaram?..
and the 16kb from VRAM?

ROMLOAD NEMESIS.ROM /S

My PS/2 keyboard has a funky layout and I'm not able to get the "/" symbol so I need to softreset to execute it after romload finishes Tongue

Given the lack of maturity of the core, it works surprisingly well. Except Nemesis2 (I'm not very good with romload parameters...) all the roms I've tested have worked mostly fine. Maybe some extra sprites flickering...

I can't wait to get my hands on my ZX-UNO in order to test this new core.

I hope it gets more development in the future.

Thanks for your work, Fabio Belavenuto.

Sprite flickering got solved yesterday. Grab the updated package.

It was actually that the last three sprites (29, 30 and 31) were not being rendered. Belavenuto worked together with FRS to have that sorted out and they ninja'd it really fast. Cool

Btw, the "MEGARAM" on it behaves as a SNATCHER sound cartridge. Not as a Brazilian MEGARAM.
