Great game thanks. It wouldn't work on my A500 mini using the config in the instructions but I did get it to work by using this one:
<game filename="scorpion_dev">
<name>Scorpion Dev</name>
<subpath>scorpion_dev</subpath>
<slave_count>1</slave_count>
<slave_default>scorpion_loader.slave</slave_default>
<slave_libraries>False</slave_libraries>
<slave number="1">
<filename>scorpion_loader.slave</filename>
<datapath>data</datapath>
</slave>
<hardware>
PRIMARY_CONTROL=JOYSTICK
PORT0=JOY
PORT1=JOY
FAST_COPPER=FALSE
JIT=FALSE
CHIPSET=AGA
SCREEN_AUTOHEIGHT=TRUE
SCREEN_CENTERH=SMART
SCREEN_CENTERV=SMART
</hardware>
</game>
Thanks.
