[Commodore VIC-20]

Regarding the greyed-out parameters, to address this you need to click on the emulation tab on the edit game screen.  Click "Use Custom Command Line Parameters" and enter -cartgeneric.  I think it's really important to have specific command line parameters for specific games, depending on whether they are cartridges or not (i.e. a single command line parameter will not be useful for everything).

You were mentioning problems with CRT files.  What ROMset are you using?  I ran a test on the following CRT file from the Gamebase20 V03 which I believe is the most up to date collection of ROMs available.

The file I tested is called

Omega Race (1982)(Commodore)-a000.crt

The version of Vice that I'm using is WinVICE-3.2-x86-r34842

I tried the -autostart again and this time I realized that if I wait long enough on the black flashing screen, the TAP files do in fact work.  I wish I knew how I could address the black flashing.  I am running VICE full Screen.

I'm also having no luck yet getting the PRG and TAP files to run using VICE 3.2.   I tried GuroDragon's suggestion of using -autostart but have not had any success.  I just get a black screen.  

[FS-UAE Save Disk]

Zombeaver states that there is a way at https://forums.launchbox-app.com/topic/43542-fs-uae-need-help-with-saving-whdload-games/

Both saving and save states work with WHDLoad in FS-UAE. Saving itself (as in using standard in-game saving) has always worked, but save states were iffy in the past. I still just use normal saves, but save states work pretty well now that relative temp has been implemented.

You need to go into Settings -> Advanced Settings and add the following lines:

unsafe_save_states = 1
relative_temp_feature = 1

Normal saves are still preferred, but I haven't had any issues whenever I've tried save states with these lines.

Here`s the trick - Right click the Vic cartridge game in Launchbox, and choose "Edit".  Click on the Emulation tab.  Check the box marked "Use Command-line parameters".   Type in "-cartgeneric" into that field.

Vic20 cartridges will suddenly work fine in VICE Vic20!  I am using Version 3.2.

Another tip, if you're looking for an easy way to exit Vice with the escape key, try the following, which I discovered at https://www.lemon64.com/forum/viewtopic.php?t=33372&sid=af3ea6ae0b8c6a35f2278b5d18f69d33

Find the file win_shortcuts.vsc, located in the Vic20 folder and open it with a text editor (for example Notepad). 
Add this line to the table: 

Code:

KEY             27          IDM_EXIT                          X

Vice can now be terminated with the Esc key.

[Import from Gamebase?]

Just wondering if there is any progress on making this a simpler process.  I have a number of Gamebases and being able to import these would be fantastic...
