Xevious FPGA arcade game on DE2-35 - update

Now with ship explosion, fujitsu mb88 microprocessor emulated

Xevious FPGA arcade game on DE2-35

Xevious VHDL source code available at https://sourceforge.net/projects/darfpga/files/Software%20VHDL/xevious
 

 PS/2 keyboard, 15kHz TV mode (only) with sound but no ship explosion ship explosion ok since 15-02-2017

Just add your own roms. 

Galaga FPGA arcade game on DE2-35

Galaga (Namco/Midway) VHDL source code available at https://sourceforge.net/projects/darfpga/files/Software%20VHDL/galaga

PS/2 keyboard, 15kHz TV mode (only) with sound but no ship explosion
Just add your own roms.

Phoenix FPGA arcade game on DE2-35

Phoenix  (Amstar ) VHDL source code available at https://sourceforge.net/projects/darfpga/files/Software%20VHDL/phoenix
 

PS/2 keyboard,  15kHz TV mode (only), with sound effects and melodies
(Just add your own ROMs)


Many many explanations about hardware and software stuff. Analog sound effects part analysis fully described with exclusive schematics and computations (NE555 oscillator, charging/discharging capacitor, noise generator).

 

FPGA64_027 with C1541_SD sources available

FPGA64 + read D64 from raw SD card (READ ONLY) + external IEC bus with DE0 nano or DE2
FPGA64 + external IEC bus with DE1

More would be too much

Don't need my own I/O board anymore Terasic put it all together : big Cyclone V, VGA, no external SRAM but plenty are available inside FPGA, µSD card, PS/2 keyboard and mouse. And not expensive at all, only audio is missing.

It seems that my future board will be that one!

C1541 drive emulation debug on DE2

Adding my own VHDL work to some other people work to get FPGA reading D64 directly from sd card. Project is already able to load many games but still bugs to find out. Debug is going on with DE2 board.
