I'm busy setting up xmas presents ;)

What's the best way to run #Stepmania or some clone of it (#OutFox, #performous, ...?) on a #RaspberryPi 3B+?

Should I run a 32-bit or 64-bit OS to get the best performance (FPS, resolution)? Which one?

Any hints are welcome! 😀

Some news about #zeST. Over the last few weekends I completely rewrote the user interface code, which should now feel much more friendly :)

It's been a long time since I haven't spent any development time on the software.

Back to the hardware side, there still are identified bugs I want to solve before next release.

A new release of #zeST is available! On the menu: support for a new FPGA board, improved floppy management, and bug fix.

Enjoy!

ok so I believe I've still got time for the next #zeST release then 😇

fyi I'm adding support for a new platform

I have implemented some undocumented quirks and glitches of the Atari ST's floppy disk controller in #zeST.

It now fully supports the Union demo's copy protection. Now one can run the internal copy program and copy the demo to another floppy image file! 😅

The penultimate release of #zeST featured, among others, two improvements:

• Complete MMU configuration, which enables the use of bus noise whatever the configured memory size;

• a cache-based, prefetch mechanism to optimise the accesses to the FPGA board's DDR memory.

Well, guess what ? The new memory management system totally blocks the bus noise “feature”, notably used in the “Ika I Compofylla" demo by Newline.

Working on a fix now.

New #zeST release! It fixes all identified loading issues on demos, plus adds some keyboard shortcuts for keyboards that are missing some keys. Enjoy!

It's been a week now that a significant part of my spare time has been used trying to solve one “demo not loading” bug in #zeST.

Currently I'm focused on the Decade demo. Problem seems to be in the MFP, in which an unwanted floppy drive controller interrupt is triggered too early, skipping the first sector when loading the main menu.

New #zeST release!

It brings a major fix in memory management, introduces “shifter wakestates” , properly implements MMU configuration, and includes other small fixes.

Enjoy!

I finally implemented the missing cache module in #zeST, in order to optimise memory accesses to the board's DDR memory. This seems to be solving the "fullscreen with nops" issue.

Expect a release in the weekend!
