CRT Characterization and Emulation
Fri, 19 Jun 2020
MikeJ
I think many people agree that retro hardware looks best on CRTs from the same period. The downside is CRTs are expensive, bulky and hard to get hold of now. I've got a small Sony PVM I use for testing, and a large Sony broadcast monitor that is most often used as a coffee table to be honest. Modern screens have...

Replay2 and DE10-nano support
Fri, 19 Jun 2020
MikeJ
Sorry it's been a bit quiet here for the last few months. I had to move flat three times since January and all the retro kit has been in storage. Work has been intense and it's only the last week or two that life is calming down enough to get the Retro stuff back on track. The initial plan was to...

Scramble video output analysis using Python and Spice
Fri, 19 Jun 2020
MikeJ
I wrote the first FPGA Scramble/Frogger core way back in 2007 (when we were all a lot younger)....   It's been ported to all sorts of other hardware with little changes, but when we were moving it to our new build system I took the opportunity to look at the video output stage again. Looking at the schematics pics below, Scramble has...

Gearing up for Replay2 Production
Thu, 21 Nov 2019
MikeJ
Replay2 is still in layout and a few things are awaiting design closure (primarily memory configuration). The FPGA chosen is a Xilinx Ultrascale+ device (super fast) with Quad core A-53s, dual R5s and a Maii GPU. The CPU section has DDR4 DRAM, and the FPGA most likely 2 x DDR3 memories. The board has a display port output for the CPU...

68060 Daughterboard rear I/O shield arrives
Wed, 6 Nov 2019
MikeJ
While there is a lot of exciting new stuff going on, I'm still trying to finish off some old commitments. Thanks to some CAD help from the team and the fantastic guys in Taiwan we have received the laser cut ATX I/O panels. Contact me if you want one. It only fits on B2 boards (not 1.0B) without modification. If you have...

68060 Ethernet and SD card support
Wed, 6 Nov 2019
MikeJ
Our resident coding genius Erique has been hard at work finishing off driver support for the DB. Source and the ROM binary in the . Please also take a look at the FAQ here: https://www.fpgaarcade.com/kb/how-to-install-and-setup-the-060-daughterboard/ The Ethernet (unlike some other solutions) relies on a 16 bit parallel interface MAC which sits on the '060 local bus. There is scope for improving performance, but...

Github release repository and Crystal Castles core!
Wed, 6 Nov 2019
MikeJ
Still a lot of work going on to move the codebase to the new github repositories and roll out multiplatform support - initially for the Arduino Vidor. Some binaries have been put here while we faff about https://github.com/FPGAArcade/replay\_release   Including Crystal Castles by the fabulous Chris B...

Amiga RTG source and driver released.
Tue, 29 Oct 2019
MikeJ
Hi all. We've released our RTG HDL files and Amiga driver code. https://github.com/FPGAArcade/amiga\_code https://github.com/FPGAArcade/replay\_amiga This uses some primitives in replay\_common. This is just a code dump to support the other projects while we faff around. I think it makes sense you reuse my code rather than do it from scratch. I'm still working to get a huge amount of stuff released including support for the Arduino...
