MakeModes on 5.23

Hi all,

Having a little issue trying to get an MDF, which worked under 4.39, to work under 5.23. Basically, it just doesn’t – it sees it, but if I select the monitor, I can’t select any of the resolutions.

So, I thought, lets load it into !MakeModes…once I found a 32 bit version (thanks to CJE Micros). However, this crashes everytime (starts with “Unknown error 4096”, and then once I get it to generate an MDF, it crashes out with fatal internal error type 2) – even running with ZeroPain.

Changing the VIDCBandLimit doesn’t help either.

Quite simply, I’m after a 1440×850 resolution for my RPCemu RISC OS 5 install (to fill my Mac’s 1440×900 resolution screen, minus title bars and Mac icon bar…or whatever Apple call it).

I know I’m missing something silly here, and will look stupid when it’s pointed out!

startmode
mode_name:1440 × 850
x_res:1440
y_res:850
pixel_rate:140000
h_timings:128,156,58,1440,140,194
v_timings:3,16,0,850,0,1
sync_pol:3
endmode

Cheers,

Gerald.

There are cowboy options. !MakeModes is a bit OTT, in addition to being a pain, truly accurate VIDC timings are not required by emulators.

When I wanted a custom MDF to fit fully into a host machine window I just took the next size up, reduced the X and Y values as required and made up the pixel rate by adding half the removed size into each porch.

More recently I had my attention drawn to OS4.39 VRPC’s rather splendid AutoMode tool in its Configuration which does generate the required MDF which will also work on RPCEmu. The following works on my iMac on both VRPC and RPCEmu OS5.23 :-

# 1440 x 850 (60hz)
startmode
mode_name:1440 x 850
x_res:1440
y_res:850
pixel_rate:75955
h_timings:10,10,16,1440,0,0
v_timings:10,0,0,850,0,0
sync_pol:0
endmode

Cheers David – works a treat.

Anymode. http://www.pi-star.co.uk/anymode/

Not silly to have missed it, people don’t realise it also works with RPCEmu

I did see a mention of it, when I was originally searching the forums, but couldn’t find any link to download it (my usual failures in searching the web again!!).

I’ve now downloaded it, and I’ll have a play later on.

Many thanks.

The CJE version is 0.27a which is from 2006 and is for the Iyonix and A9home.

I only checked that out because this ROOL CVS change appeared this morning for !MakeModes 0.31

I believe !MakeModes is in the RCnn images but it is not in the HardDisc4 Nightly Betas. I have built it from CVS on a Raspberry Pi Mk1, in ARMv5 mode to accommodate !CVS, and the result does start on the Pi in ARMv7 mode.

Unless I’m misreading that’s making sure to avoid a zero value parameter on entry and avoid a ZPP error
