Re: Running Wonderland from a hard disk

Thanks for your reply. I tried naively replacing the harcoded SCSIFS::4 and ADFS::4 strings in the win1 binary with IDEFS::4, taking care not to modify the size of the file. The game still crashes in the same way. That's just the issues I could remember, I've now looked at my notes: ⋅ Whe...

Re: Running Wonderland from a hard disk

Has anyone come accross this issue before? If not, I might give ADFFS a try. The game has a couple of issues in its loader, it will generate an Abort in RISC OS if the disc it's running from isn't named and will only run from either ADFS::4 or SCSIFS::4, which are hardcoded. It's next on my list of...

Re: Drop Ship Joystick support

The original Man At Arms is the same, there's a Joystick option in the controls but no Joystick interface is touched. The manual doesn't mention Joysticks and examining the code it only checks the keyboard and mouse. Is this another Voltmace title?

Drop Ship Joystick support

Drop Ship says it supports Joysticks in the manual and there's a Joystick option in the Controls options, but it doesn't appear to talk to any Joystick interface.

There's a fairly comprehensive list of which games support which interfaces here. The list was compiled by monitoring which interfaces games attempt to talk too whilst running.

Re: Vertical Twist / Serial Port Joystick interface

Unfortunately not, the documentation that came with the interface doesn't cover VTJoystick_Define and only briefly mentions some of the other SWI's.

Thanks for the link though, I believe that's possibly one of the last revisions of the manual.

Vertical Twist / Serial Port Joystick interface

Does anyone have the games developer SWI documentation for this Joystick interface, in particular what the table passed to VTJoystick_Define specifies.

The driver disc doesn't go into detail on the SWI's, but several games use Define so there must be detailed documentation on it somewhere.

It's probably less than 30 lines of code...as this is on RISC OS 3.11 you can simply write over the SWI vector in Page Zero to redirect to yourself, no need for any legal calls.
