TwinWorld: Works natively. 32bit Patched version. Patch can be found here:
https://sites.google.com/site/jeffreyadoggett/TwinPatch.zip
*Silent. No music or sound. Sounds great on Pandaboard.
*It must be played in ArmV5 emulation CPU mode. Otherwise it eventually hangs.
*It's smoth as silk IF you edit it's !Run file and set it to refresh "every frame" and boot with a 50HZ mode in config.txt. hdmi_group=1 and hdmi_mode=17 set a 50Hz mode.


Starfighter 3000: Works natively.
*Flickering HUD, almost invisible.

PD: Zool 32bits IS smooth if you edit it's !Run file to refresh every frame and set a 50HZ mode as described. It's rock-solid 50 frames per second and perfectly synced.

You need the 32-bit version of course. The patch to update any Star Fighter 3000 to version 3.14 (latest) is available here. It works perfectly when you play it in the desktop. Flickering HUD is a full screen only issue.

BigBang: Works natively
Nebulus: 26bit module needed.

btw, how are those 4bit video modes defined? I only see geometry and timming data in mdfs...

The version of BigBang found here http://www.acornarcade.com/forums/viewthread.php?newsid=879 needs a little tweaking: Commenting out the line "rmload <BigBang$Dir>.z15" in the !Run file.

The colour depth isn't explicit defined. If you request a not supported colour depth, the OS will give you the next best thing. In this case a 8 bit mode.

@Holger Palmroth: Yes, sorry, BigBang needs that little tweak.

Elite: Doesn't work. 26bit module (CLockUtils). So near, yet so far! unhappy

Mad Professor Mariarty: Doesn't work. 26bit modules.

BugHunter In Space: Doesn't work. 26bit modules.

Work under ADFFS:
Conqueror
...
Non-working, require video memory remapping:
Zarch
I had always assumed they used the same game engine as they looked similar, so when I saw Conqueror on the working list I got excited at the thought that Zarch would work too. Would love to have been able to show that at the next Raspberry Jam.

The Pi doesn't support 4bit modes, I need to code a backbuffer with bitplane conversion before they'll work correctly.

Elite: Doesn't work. 26bit module (CLockUtils). So near, yet so far! unhappy
I need to get this and Zarch running natively on the Pi, so I'll take a look (Kris Adcock has kindly posted the Elite floppy to me, so I'll start on it when it arrives). I suspect most 26bit modules can be made to run under 32bit with little change.

They do, except for one minor change...in Conqueror it requests the screen address and in Zarch it assumes &1FED400.

Be warned that there is/was a bug in Elite which can cause it to write outside screen memory and crash. The version available in our downloads section has had the bug patched, plus I've removed the 5 or so layers of encryption surrounding the main executable (previous versions worked around this by disabling the cache during loading, but since I needed to patch the bug I figured I might as well do it properly). Plus the disc copy protection has been removed (if there ever was any disc copy protection? I've only worked from the free copies available online)

If you're lucky (and interested) I may be able to find the original code I wrote to apply the patch to the game.

Send it over if you can find it, it will certainly be useful later.

Looking at the patched version, the main code isn't ARMv5+ safe. However...one step on from that, its written in C and CLib reports it's not 32-bit compatible (I presume it's CLib generating the error) - What does CLib check for? Does it need a flag somewhere in the code?

Indeed. That "updated to work on all RISC OS machines" comment is a bit out of date wink

The 32bit CLib uses a different initialisation SWI (not sure what it is offhand - sorry!). So 32bit-only versions of CLib just return an error when the old 26bit SWI is called.

XSharedCLibrary_LibInitAPCS_32

Sadly, its not something that's fixable by hand - it will need recompiling.

On a positive note, I have Zarch sort of working. Something on RO5 however, is resetting the abort vectors back to defaults - which knackers my Data Abort handler.

The other issue is the bug-ridden USB drivers on the Pi, which cause the keyboard/mouse to die very quickly - so it's unplayable. The demo works fine though.

Hopefully this will be included in the next ADFFS release, if I can figure out how to fix the abort vector resets.

EDIT: Ignore the Abort reset bit - that's another game having that issue, I suspect it's a C library inserting abort handlers.

Attached is an archive of my elite patch sources, and a copy of the compressed, encrypted binary that the patch was designed to work with. The readme should hopefully explain all you need to know.

Thanks Jeffrey.

I tracked down the Abort issue with Zarch and it looks like a "feature" of RO5/Pi. When mapping a doubly mapped page, the OS subsequently reports it as being -&400 from the address it's actually at. I've reported it on ROOL.

I've found several other "features" in the OS, that I need to create Repros and post. Finding where they are takes some time though!

I remember reviewing Serpents. As a 20ukp commercial double-pack (if memory serves) it was a bit "pd", but it was a fun, if simple game.

Deadline, however, has passed me by completely, which I'm quite shocked/surprised about. Who developed/published it?

Ah, Network 23 - didn't realise they'd released anything other than Warlocks. That was an excellent game, as I recall.

(Goes and reads wiki) Ohhh, and Provocator, eh? That was another fun-but-not-oft-remembered one.

Might the change also fix occasional keyboard and mice dying or auto repeating last key?
As apparently Raspian also suffers from it I expect it's a USB driver problem.

Thanks for those screenshots.

There are quite a few games I've never seen on the preservation project list. Could you do screenshots of some of the more obscure ones, like the Eterna and Coin-Age titles?

I will, but I'll do it on the preservation thread as this one is specific to games on the Pi.
