Thank you for the report, and for supporting Sky Shapers!! Great news that the game runs on A500 mini with custom firmware! I love the setup you got there :)
Hi.
This is the instruction I got from CoffeeCupArcade.
What you will need - A500 Mini, AGS 2.7 installed onto a USB card, LHA version of game.
Step 1 - Install AGS 2.7
Step 2 - Unzip the .LHA version of the game and take that extracted folder and place it in the AGS 2.7 "Shared" folder.
Step 3 - boot up AGS 2.7 and hit escape on the keyboard to drop into Workbench.
Step 4 - open up the "Shared" folder and launch the game per normal.
Hope this helps!
