ACSI2STM

⚠️ WARNING ⚠️

This ACSI2STM firmware should treated as experimental and only be used if you've backed up your SD card and are comfortable re-flashing your firmware via USB if anything goes wrong.

What is this and why do I need it?

This firmware resolves a bug that prevents Atari ST software built using MiNTLib (m68k-atari-mint toolchain), like STDOOM, from detecting and loading files from an ACSI2STM using GemDrive. Take a look here if you want the technical details.

So, if your WAD can't be found, then this is the firmware update for you.

Installation

There are 2 versions of this firmware available:

• acsi2stm-5.1b.ino.bin is based on the latest official v5.1b firmware and should work with any ST
• acsi2stm-5.1b-mste.ino.bin includes the Mega STE only 5.1tin fix for using 16MHz with cache mode

To install the firmware:

1. Download the appropriate firmware for your Atari ST
2. Rename it HDDFLASH.BIN
3. Put it in the same folder on a floppy disk or SD card as HDDFLASH.TOS
4. Run HDDFLASH.TOS from your ST's desktop
