ADFFS 2.71 beta

[JonAbbott]

The packaged beta of ADFFS 2.71 is now up for testers, as is Fervour which now works - with the usual Wimp caveats. It does randomly hang when going into the Wimp based options, which I've been investigating but haven't figured a workable solution yet.

I've made some substantial changes to the way the stack is setup when 26bit Module entries are called to resolve reentrancy issues; they're now allocated dynamically on Module entry and released on exit, so each entry point is using a unique stack. At some point I'll extend this to IOC and IRQ interrupt entry points.

The following WIMP games work:

• F1004301 Black Angel (1992) (The Fourth Dimension)
• F1007401 Chaos Engine, The (2000) (R-Comp Interactive)
• F1013001 Elite [v1.02] (1991) (Hybrid Technology)
• F1064501 Elite [v1.14] (1999) (Ian Bell)

The packaged 2.71c beta is now available for testers, along with the following packages for testing:

• F1021901 Karma - The Flight Trainer (1992) (Periscope Software)

2.71d beta package now available for testers, along with:

• F1017101 Global Effect (1995) (Eclipse)

When prompted for the protection, press SPACE, which appears to bypass it.

I've noticed the screen size in Cartoon Line part one (UCS) is incorrect under recent RISC OS 5 builds. It started sometime between the 01-11-18 and 16-11-18 builds, so is related to the changes to the MODE change process. Other games that alter the screen geometry may also be affected.

On further investigation, this appears to be a bug in the game. I've fixed the package/obey.zip locally and they'll be distributed with the next update, in the meantime the fix is to add the following to the boot script / !Run:

Code: Select all

IF ADFFS$OSVersion>=&50000 THEN JITMEMORYA 8300 1A000011 2A000011

The game issues OS_ServiceCall &50 to see if MODE 9 is supported. If it is, it then checks the VIDC List type returned, but wasn't checking for type 3 correctly.

Vubars in Overload (2000) (Paradise Games) help pages cause a crash

2.71 fixes this issue.

@Jon: I see Elite listed as supposedly working. I have installed it via Packman, along with the latest ADFFS beta, and it crashes here. Do you know what's going on?

I have also noticed that some games don't install right from PackMan
-PacMania [Learning Curve], Mad Professor (Standalone version), PipeMania (Standalone version), Stunt Racer 2000 [SA version], Pandora's Box [SA version], Cataclysm [SA version], Chocks Away Compendium... All these install into directories with numbers. PacMania installs into a dir called 1044700, etc.
Maybe it's intentional to install them in different locations so they don't overlap with the versions you consider "the most popular" ones?
-Zarch [original version, not the 32bit one] installs ok but lacks icon, a generic icon appears instead.

Also, I have observed that Zarch in 32bit version runs choppy on 50Hz video mode. Original version runs perfectly well.

Appears to be a bug. OS_CallASWI and OS_CallSWIR12 calls that need to bypass the JIT aren't being passed to the OS correctly.

Where there's a duplicate !App folder, they currently end up in a subfolder based on the game ID. I've yet to go through all the games and rename the !App folders so they're unique.

-Zarch [original version, not the 32bit one] installs ok but lacks icon, a generic icon appears instead.

25 currently don't have icons. Zarch isn't one of them though, so I'll fix that on the next update.

I have observed that Zarch in 32bit version runs choppy on 50Hz video mode.

Terminate ADFFS before you run it. Zarch32 is coded to run native on the Pi, ADFFS however is taking over and emulating all legacy MODE's, including MODE 13.

@Jon: Thanks for the responses! Will keep up with the updates and tests. This is getting better than ever!!!

Appears to be a bug. OS_CallASWI and OS_CallSWIR12 calls that need to bypass the JIT aren't being passed to the OS correctly.

I examined the 2.68 code and couldn't honestly see how it was working in the first place. In 2.68 the JIT SWI dispatcher calls the JIT and asks it to construct a codelet for the SWI OS_CallASWI wants to raise, when the SWI in question needs to go directly to the OS; it then hands off control to it. It didn't however appear to be doing that and looks like it was overwriting the original "SWI OS_CallASWI".

The initial idea was okay...use a codelet...but it really needs to be a codelet containing OS_CallASWI, not the SWI it's trying to raise. SWI affected by this are OS_IntOn, OS_IntOff, OS_EnterOS, OS_LeaveOS (not sure any of these are actually legal in this sense, but we'll cover our bases so to speak!), OS_CLI, Wimp_Poll and Wimp_PollIdle. Moving to a codelet for OS_CallASWI and OS_CallASWIR12 however neatly removes the need for any special treatment.

The packaged 2.71e build is now available, which fixes this issue.
