The first four prototype boards have had the FPGA BGA mounted. I'll assemble the rest of the parts during the week, so we are aiming for a fully assembled Replay board for power on test by the end of the week. All the connectors and components I have tried so far fit on the board :)...

There may be some disruption over the next few days as we are moving to a new server...

... is nearing completion (really, honest). Placement is complete and routing is going well. I hope to get some pictures up in a week or so. It is an ECX size board measuring about 14cm by 10cm and designed to fit in a case. It has a large Spartan3E Xilinx FPGA, quality audio and video output (including DVI) and a PIC...

I have updated the VIC-20 code to run on the Xilinx Spartan 3E board. It now supports cartridge images held in the on board flash memory. I have fixed a timing error in the T65 code and this has been updated also (Library page)...

Well, it's been a little while since I last posted any news. I have completed the four Atari ST ASICs and am co-simulating them. I am in final stages of designing a low cost FPGA platform which will be ideal for the games, but also for running the Atari and Amiga (MiniMig) FPGA clones on. It has an expansion connector into...

Arnim Läuger has reverse engineered some Konami custom ICs. As he has kindly released the firmware you can use the 28 pin modules available on the Parts page as replacements for these devices. It has been a busy month for me, I've been in Asia a lot again. I am celebrating completing the reverse engineering of the Atari ST Glue custom...

I survived the mud at Glastonbury Festival! Had a superb time, met lots of great people. Right, there is no way round it, I am going to have to write a DDR memory controller for the Spartan3E board. The ones that are out there are not flexible/high performance enough for my Asteroid needs, and I cannot modify and redistribute the Xilinx...

At long last (almost two years) I have completed the Scramble / Frogger code - I am easily distracted! The hardware is very similar, so I have added a compile time switch to allow it to run both games. Many other games can be run on this hardware, so I am sure a multigame will be produced at some point. This...
