It's a bit tricky to get stable builds now as the fpga is over 95% full. However there was some work done on the sdcard reader that I haven't tried yet. My sdcard became corrupt after heavy usage, so I need to reformat it. Please let me know if anyone has tried the newSD branch from github. Otherwise I will give you an update once I have tried it!

Do you have any binary of the new branch?

Hello,
There is no bitstream (.rbf) file available for download, I have built the project but not tried it on the MiST yet. I will put the file on the mist-binaries repository once I have make a quick smoke test.

FPGAGEN Beta (2017-05-18) released :megaphone:

Please find the file:

Code: Select all

fpgagen-beta_20170518.rbf

under:
https://github.com/mist-devel/mist-binaries/tree/master/cores/fpgagen

I have done a quick smoke test, and the games I that usually play are working with sound. The game loading seems to be a bit more stable since the NewSD fix (see above)

:cheers:

Code: Select all

This is a port of fpgagen - Genesis/Megadrive core to additional platform(s)
MiST, Turbo Chameleon 64, Altera/Terasic DE2 board

The core shall be considered a work in progress as there are multiple issues:
1. Sprite flickering on heavy scenes, or on large sprites
2. No LFO modulation of the FM sound
3. Rom file formats supported are .bin and .gen, no support for .smd files
4. The design does not fit on the Altera/Terasic DE1 board anymore

==== Installing the core ====
If you are not buidling the core, copy the following files to the root of your sdcard:
fpgagen.rbf
Config_VGA/FPGAGEN.CFG, or Config_TV/FPGAGEN.CFG (for 15 kHz video)

Then rename the file fpgagen.rbf to core.rbf

I've tested the core. OSD is too buggy and gets corrupted soon. But great progress on games :D, although most racing games have corrupted graphics, like Super Monaco GP.

Keep the good work!

Regards,

Salva
