I personally doubt I am going to see your hardware still in this life. Please do something with this Mike before most of us on this forum go extinct!

<![CDATA[Current state of repos]]> http://www.fpgaarcade.com/punbb/viewtopic.php?id=1223&action=new I've made a few changes the the replay_lib , global settings for audio / keyboard input from ARM to allow bridging from debug serial/usb.

The Amiga core is having some changes done and may not compile at the moment.

I've added a getting_started simple project as well, which is just a shell to use when starting new projects.

<![CDATA[Modelsim simulation]]> http://www.fpgaarcade.com/punbb/viewtopic.php?id=1219&action=new Quick start guide if you are using Modelsim.

in the modelsim.ini file I setup :
work = $HWLIB/work
unisim = $HWLIB/unisim

Define an environmental variable HWLIB. I use


From a command prompt under Windows at least run :


This only needs to be done once. It compiles the Xilinx unisim libs. If you are not using ISE14.7 change the path :
#rem set to your source of the Xilinx UNISIMs library
set XILINXPATH=C:\Xilinx\14.7\ISE_DS\ISE\vhdl\src\unisims\
set XILINXPATH_V=C:\Xilinx\14.7\ISE_DS\ISE\verilog\src\unisims

Run this every time the replay_lib is updated :

Then the core tb :

then you are good to go.....
vsim a_replay_amiga_tb

I have a handy script which adds a restart and rerun button
source restart.do

<![CDATA[mass storage]]> http://www.fpgaarcade.com/punbb/viewtopic.php?id=1217&action=new Thanks for the advice Jim, I'm indeed using 10 bytes. Going to change that for 12 then to avoid any problems.

<![CDATA[Best LCD Monitor for Replay]]> http://www.fpgaarcade.com/punbb/viewtopic.php?id=1214&action=new Agreed, I've been using the BL912 and it's just the perfect screen for the replay. I'm using it with all my other retro gear (xrgb mini, A4000/PIV, A1200/mk2)

<![CDATA[Williams (Defender, Stargate, Joust, ...)]]> http://www.fpgaarcade.com/punbb/viewtopic.php?id=147&action=new Was there ever any more progress with this? I did a number of arcade and pinball sound boards in VHDL a year or two ago and ran into the same issue with the 6800 core. It sounded ok but when I compared it side by side with the sound from my real Robotron cabinet it was clear that the speed was off.

A cycle accurate 6809 would be great, it would enable an FPGA recreation of the Vectrex. All of the major components already exist in HDL but the Vectrex relies on precise timing to draw the vectors.
