Hi All, I've made a new release of my PAL/NTSC C64 core called FPGA64. It's version 0.21 released on 20070709. In this release a lot of improvements for the...
A first post here... I've just started playing with FPGA-64 in my new development board I've received a couple of weeks ago. It's a Xilinx/Digilent Spartan 3E ...
Hi Magnus, For loading and saving games I run a 1541 drive emulator on the PC called 64HDD (there are others too). For the C-One it is simply connecting the...
Thanks for all your great advice Peter! ... Ahh ok I have a look at that, but it would be nice to have the card handle its own files. Maybe a MMC/SD-controller...
... Magnus/Peter, is the XESS board project (fpga64_xess_xsa3s1000.vhd) the most 'feature complete' version of the project? I ask because I'm currently...
I was under the impression that the 'fpga64_cone.vhd' is just a suitable top-level for Alteras and that the "xess" is the same thing for Xilinx-devices.. Ohh...
Just though I would give a big YES, FPGA-64 now has a working SID. I've only tried the simplest BASIC-program but it sounds like in VICE. Now I want a way to...
... They're trivial pwm adc/dac implementations. I have an audio DAC on my platform already, instantiated at the top level. So instead of using the DAC for SID...
... Woo hoo - working SID here too!!! <http://members.iinet.net.au/~msmcdoug/pace/platforms/platforms.html> I might have a look at implementing IEC+1541 within...
Hi All, With the recent discussions on porting the FPGA64 project, I though I would share some information about a IEC implementation I have used in the past. ...
Hi, i have managed to work the fpga64 core on my spartan 3 board,too. It is still without SID because i donīt know how to replace the missing parts in the SID...
... I should explain that I'm not using the DAC inside the SID, so clk_DAC and audio_out aren't used, and I punched out audio_data (voice_volume) to my top ...
Hi Mark, thank you very much for you help. The SID works now,the iec bus,too.So i can load programs for testing. In some games the sound is o.k. in other i.e...
... The only test I've done is a 6-line BASIC program I found on the net that outputs a saw-tooth that decays after a few seconds. I'm yet to hook up anything...
The sram access on the c-one board is little different than the access of "normal" srams on fpga boards. I have used the part from peters fpga64 version for...
Who have ported FPGA64 to Spartan-3E ou Altera DE1 boards? Cand anyone send me these ports? Thanks, Roni [Non-text portions of this message have been removed]...
Peters FPGA64 source packages contains a top-level design for the xess-xsa3s spartan 3 fpga board. With some small modification it works with other spartan 3...
I've got a stability problem with FPGA64 and I'm not quite sure where to start looking. I'm suspecting it has something to do with external SRAM, but I'm not...
... pressing ... Same behaviour like my spartan 3 board. I always have to press the reset button,too. The c-one core starts without a button press. On my board...
... Interestingly, the same project ported to an Altera EP2C35-based DE2 board runs from cold-configuration and appears to be stable. On my own EP2C35-based...
Hi, I've seen the reset failing on other boards. What you could try is increasing the number of reset periods during startup. It is a generic parameter on top...
