WePlash does not require VBXE to load. when i tried to run the Sillyventure pack BATCH file the 1st time i a also got the '"Weplash data not found:EF03 E0E0E0E0" message and i suspect that the SIDE CF image was not loaded to proper location, strangely after rebooting my PC and running the batch file again everything worked fine.
if you have SIDE2 cartridge you can burn the .IMG file to a CF cart using WINIMAGE tool, boot the ATARI COMPUTER with SIDE2 in spartados x mode and the demo will play automatically on any Atari XL computer.
if i had a MYIDE2 cart i would probably could make the demo work on that cart as well.
This has given me an idea though. Normally MyIDE 2 is MyDOS & MyBIOS based, but thanks to FJC's SpartaDOS X drivers for MyIDE, 2 you can set up MyIDE 2 to have SpartaDOS X in sram or, like I have, the actual SpartaDOS X cartridge with pass-thru. My point is, I will see if I can get your demo running through MyIDE with SpartaDOS X using FJC's driver.
