Last post by Prodatron - 13:08, 12 May 25Quote from: GUNHED on 22:40, 11 May 25Its great Multitasking OSNo, in Rosanne there is no multitasking at all. There is not even "multi-programming".
As soon as you go back from the current program it has to store its document and shut down itself again before you can do anything else. When returning from a program and switch to another one, which was already running before it lost all its states and needs again to load an existing document or start a new one.
The UI concept is similiar to the NC100/200, nice designed, lot of easy to use keyboard shortcuts.
But Rosannes display routines are just terrible slow. The screen is 38K, but the CPU is 4x as fast as these of the CPC and NC, and you can watch, how it is plotting things from up to down line by line.
Maybe some like this because it gives some retro feelings, but with a 16MHz Z80 you can expect a lot more.

I have a sneaking suspicion you may not get audio on a Plus machine if you don't, but someone would have to try to be sure. Shortcutting what you were supposed to do with the PPI was the tip cause of incompatibilities.

Last post by ikonsgr - 12:27, 12 May 25Well, this must be the weirdest problem i ever encountered regarding dsk image access... 
The game has a Basic loader that loads multiple files in the extra 64k ram of cpc, but for some unknow reason, loading of a specific file (PROGD.ZX0) causes a severe hang-up error of the usb host module that even hardware reset can't fix!
Of course as already noted, using the "direct file" form of the game, not only works perfect, but loading, is ~3-4 times faster than using the dsk image! Btw, this should be a "lesson" to all CPC users (especially CPC 464 ones):
STOP using ALL THE TIME the bulky and slow dsk images, but whenever is available, USE "DIRECT FILES" (or "mass storage" form)!
Anyway, i tried to resolve this problem, and in the end i manage to make game load from a dsk image!
First, i transfer the dsk image to a real floppy disk (using a CPC 6128 of course), and loading from it worked perfect, that confirmed that this is some a kind of weird "bug" of the usb host module. Unfortunately creating a dsk image from the floppy disk, still didn' work.
So then, i tried a more "extreme" approach: I formatted a floppy disk, and using |COPY i transfered all files from "Direct file" form of the game to the floppy disk. Then using |DISK command i created a dsk image of the newly created disk of the game, and guess what, this time worked perfect!
You can find the modified/working dsk image of the game here: https://www.dropbox.com/scl/fi/zhxcr9vbpe2owyayyzfcd/BOMB2.DSK?rlkey=4rqc827ku86f0bkf5soj9936p&dl=0
Still, i wonder, how exactly the developers created the dsk image, as it seems that something in their method, is the real "root" of the problem...

Quote from: Emu on 09:44, 12 May 25I tried with Samsung Notes and Whatsapp, both keyboards work correctly.Quote from: ikerkaz on 15:12, 09 May 25only the numeric keyboard and the enter key working... maybe some kind of bad configuration in my side?
Does the keyboard work correctly in other apps than emulators?
If not: I found hints on the web according to which NUMLOCK might be the culprit, e. g.: https://www.reddit.com/r/SamsungDex/comments/spj8yp/recent_weirdness_with_bluetooth_keyboard_s10/?rdt=51142
Inside your emulator, I pressed NUMLOCK in order to check the behaviour. The numeric keyboard works like a joystick or not, depending of the NUMLOCK status. This is the only difference; the letter keys don't show on screen with NUMLOCK pressed nor unpressed.

Quote from: McArti0 on 00:59, 11 May 25No. Writing to register F6 is completely unnecessary.
Really? I mean everyone in history of CPC always used 3 OUTs for sending one "sample" to the PSG (e.g. see actual Arkos Tracker MOD player).
See here:
https://www.cpcwiki.eu/index.php/How_to_access_the_PSG_via_PPI#Writing_to_a_PSG_register
This part, which is using 3 OUTs...
Code Select
ld b,&f4 ; setup register data on PPI port A
out (c),a ;
ld bc,&f680 ; Tell PSG to write data on PPI port A into selected register
out (c),c ;
ld bc,&f600 ; Put PSG into inactive state
out (c),c ;...is done in every sample player, see e.g. AT MOD player:
Code Select
ld b,e
out (c),a ;#f400 + value.
ld b,#f6
out (c),a ;#f680
out (c),0
Same for Lightforces first example.
Would be funny, if we were all wrong in the past.

It's the latest version with music and other improvements. The left/right scrolling is triggered sooner, so you'll see incoming enemies more clearly (following a suggestion of Onevision).
RUN"FIRE2" at startup to use a Joystick with 2 buttons. Pressing both buttons launch a grenade.
RUN"FIRE3" to use a 3 buttons joystick !
More speed optimizations in the code.

Quote from: Jean-Marie on 03:34, 12 May 25Okay, I've had an idea. I've put the files on a classic 178K AMSDOS Dsk.Ok. I will try it when I return. This is the no music version ori the music one?
Obviously, I could not store all the files, but you can still play the 5 first levels.
Can you turn off PARADOS and run the disc please? This way, we'll know if the problem stems from PARADOS!
