pcem4crt - pcem mod for crt v17.4

[haynor666]

Any difference ? I had bad scale mode. Should be 0 instead of 1.

[haynor666]

Another bizarre example - 320x191

Uo! You are right, with scale_mode = 1 looks more fuzzy.. scale_mode = 0 looks better!

EDIT: Updated release https://github.com/psakhis/pcem4crt/releases/tag/3

Thx haynor666

Hello
Is there a tutorial specific to pcem4crt ?
I successfully configured a 486dx2 with french MS DOS 6.22 img on the normal pcem v17 and plays some games.
But when I try this img (or other i find on the net that work on normal pcem), pcem4crt always aks me for a floppy on drive A.
Is the floppy mentionned in the recommendations section mandatory to launch pcem4crt ?
If yes, where to find or create it ?
A another big question for beginner is how we can quit pcem ?
Thanks.

Hi @pixel69, i will try to resolve some questions.
1) Same configurations on the normal pcem v17 works with pcem4crt. Under "nvr" directory you have bios files with saved configs (amibios, etc.) You need to copy too or enter to bios again and configure ide hdd and floppy disk pressing "supr" key at boot normally.
2) About pcem4crt asks for a floppy: check if your bios are detecting hard drive on configured machine entering to the bios
3) Quit pcem isn't easy at all, i recommend run autohotkey script to kill the process. For example with this 2 buttons pressed in my case
#Persistent
#SingleInstance force

Joy10::
if GetKeyState("Joy12") {
   ifWinExist, ahk_exe %1%
       {
           Runwait, taskkill /im %1% /f
           ExitApp 
       }
}       
return

my problem was that the hdd was not enabled in bios (AMI WinBIOS 486), i just configured the boot sequence.

For now I have just tried it in very low PC (1Ghz AMD APU: A6 1450).
I have configured a 486DX2 and a 386DX33 machine, 16 Mo and Tseng ET4000AX for both.
pcem switch well from interlaced mode (when in dos) and progressive 240p
I tested Desert Strike and Super Frog.
The emulation of the 486 is too slow.
With the 386, is still slow for desert strike.
super frog seems to play at nearly normal speed but the scrolling is bad.

When it will be possible, I will test on my new dedicated CRT PC (Pentium 3Ghz, Radeon R5)

Hello
I released a SDL2 build for midi output and network on Windows.

This build is compatible with Munt and Roland MT-32 devices.

(*) Updated wx-sdl2-display.c for linux builders with latest switchres changes.

WOW!
This is really what I needed for my IBM CRT.
Looking to cut down my real retro pcs ideally to just my working machine with dual monitor setup and emulators like this great one.
Thank you very much!
