Re: RiscPC support

An observation. On the A4000 JP goes to 640x350 @ 70Hz. I get the same settings on the RiscPC, but the display is garbled - this is fixed by increasing VCR by 20, which results in 720x400 @ 67Hz if I don't correct the pixel rate.

What does that tell us?

Re: RiscPC support

I've tried fixing xBSR to xDSR and xBER to xDER for H and V and Red Squirrel still locks up with Boogie Buggy when LCDGameModes is on and borders are displayed. However...according to the TRM, to turn borders off HBSR=HDSR and HBER=HDER - but this doesn't seem to be the case, it looks like it should...

Re: RiscPC support

I think there may be an issue with borders. Quite a few games hang under Red Squirrel if I turn "Display borders" on, implying the borders are overlapping the display.

Should we track the parameters and alter borders if they're inside HDSR/HDER and VDSR/VDER?

Re: kryo2apd

I'm getting an error trying to convert Boogie Buggy disc 1. All three APD's have corruption, so something odd is going on. This is using the version on the dev site. Exception in thread "main" java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ...

Re: RiscPC support

I've a feeling just from playing caverns on the A4000 with LCDgm running that the ship position is out slightly, compared to monitortype 0... Think this must be down to the LCDgm mode parameters. Am I right in thinking Caverns is 256 colours and ManU is 16? I checked Caverns on the A310 against Cav...

Rotor

An interesting one to fix...it changes palette part-way down the screen and attempts to turn the video off a bit further, to hide what looks like code in the video memory. It works under RO3.11 emulation with monitor type 0, but fails miserably on monitor type 4 or RO above 3.11. Unfortunately it do...

Games requiring Kryoflux imaging

There's a few games that we need to image with a Kryoflux as the protection may talk directly to the FDC via IOC: Adventure classic collection (TOPOLOGIKA) Blaston (Eterna) (confirmed direct FDC access) Bubble Fair (Eterna) Cartoon line part one (Eterna) (confirmed not using direct FDC access) Chequ...

RISC OS 3.7 mouse pointer issues

I've noticed several issues with regard to the mouse pointer in RO3.7 compared to RO3.6 and below: 1. Caverns - the pointer is only showing on the bottom half of the screen (caused by OS_Byte 106, 2 ) 2. Manchester United Europe - the pointer moves smoothly on RO3.6 and simply jumps between position...

Re: RiscPC support

Compared to RO3.11, the ship is also out slightly, being down and right a bit, so our cursor correction may be out slightly or need to be bit depth specific. Manchester United Europe is spot on. I've checked both Caverns and Manchester United Europe on RO3.5 against physical A310/RO2 on analogue mo...
