Re: [Rpcemu] RPCEmu pre release test version 0.8.100

Hi there! Apologies for not providing more details.

Host OS: Windows 10 64-Bit (Intel i5 CPU)

Emulated OS: RiscOS 3.71

Settings: Default (2MB VRAM, 32MB RAM)

After more in-depth testing, it appears to be an issue with the UniBoot2 archive from https://www.retro-kit.co.uk/user/custom/Software/Acorn/RISCOS/UniBoo2.zip when !Boot or !Run gets executed whether it be at boot time, via display of the directory or directly.

To reproduce:

Install fresh copy of RPCEmu 0.8.100 and add RO3.71 ROM

Add UniBoot2 to the root of HostFS

Run !Boot or !Run by any method

Behaviour for each HW configuration (apart from Phoebe) is as follows:

Interpreter

--------------

ARM610/710/StrongARM/A7000/A7000+: Works

ARM810: RPCEmu Fatal Error - Bad LDRH/STRH opcode 0000ADB8

Recompiler

----------------

StrongARM: Works
ARM610/710/A7000/A7000+: RiscOS locks up (although the mouse pointer *usually* remains working)
ARM810: Some garbled RiscOS error box that just recurs if you try to cancel it

Erm, this doesn't happen here, as such let's try to reproduce it.

- What do you mean by crash? Emulator exits? with or without error
  message? emulator stops running (lock up)? Error reported in RISC OS?
  something else?
- At which point does the 'crash' happen, on boot? on accessing a
  particular file? something else?
- Which version of RISC OS are you running?
- What files have you put in HostFS, a boot sequence? which? something
  else?
- What settings are you using for, memory, vram?

Can you also post your rpc.cfg and rpclog.txt files.

>    Think you must already be aware of it

This isn't directed at you particulaly, but to all users of rpcemu.

We really really need people to report all the bugs they find, there are
so many potential configurations and pieces of software out there that we
can't run everything, as such the chances are that we're not aware of it.

But every good bug report stands a very good chance of being fixed which
makes everyone's life a little better.

Even if you figure out a workaround (e.g. change setting to something
else) please still report the original issue.

> is there a list of known issues somewhere?

There isn't at the moment, I'll look into adding one.
