My last problem - the TRS80

BuZz

@mitu Sounds good. Feel free to pass anything my way also. Cheers.

sdltrs-model4p-cas = "/opt/retropie/emulators/sdltrs/sdl2trs -fullscreen -nomousepointer -showled -m4p -romfile4p /home/pi/RetroPie/BIOS/level4p.rom -cas %ROM%"

The option for loading cassette images is -cassette or -cass ...

As that makes me think upstream needs an automatic mode, which could be requested maybe

Automatic media detection for a few use cases? Probably not ... :-)

Swapping -flop1 in EMULATORS.CFG for -cass has got me to the OS, many thanks to all. Now when I type CLOAD the tape counter appears and runs, but nothing happens when it reaches the end :(

Loading programs from cassette was always a pain in the "old days" because it depended on various factors: volume of the recording and quality of the tape ... and mostly only succeeded by chance ... ;-)
You can only load BASIC-programs with CLOAD, for programs in "machine-language" use SYSTEM ...
Not all CAS-files of the internet will work in the emulator ... so please provide more details ...

Don't know if it will work on TRS80 but with MSX you had to do :
cload
run

You can try that.

@folly I don't get the command prompt back after the load.

@jengun @jengun Okay, so I'm trying to load SeaDragon, as seen here:

That video shows the game is loaded with SYSTEM followed by S, and if I do that then the tape spins up and loads for about four minutes. But after that nothing happens and I'm just left looking at this:

I'm still getting nowhere with SDLTRS, so I'm using LR-MESS:

lr-mess-trs-80-cass = "/home/pi/RetroPie-Setup/scriptmodules/run_mess.sh /opt/retropie/emulators/retroarch/bin/retroarch /opt/retropie/libretrocores/lr-mess/mess_libretro.so /opt/retropie/configs/trs-80/retroarch.cfg trs80m3 /home/pi/RetroPie/BIOS -cass %ROM%"

I'm just hitting Enter when the "Cass?" and "Memory Size?" prompts come up. And as I said it's the CAS file from the most recent MAME softlist so hopefully it's not the file that's the problem.

No idea which CAS-file MAME is using, but this works with SDLTRS in Model I-mode ... in Model III-mode you have to type L after Cass? to select 500 Baud to load and save tapes for the Model I ...

@jengun

You can only use .wav (cas files) with TRS-80 (trs80) on mame/lr-mess.

This is the output from mame :

pi@raspberrypi:~ $ /opt/retropie/emulators/mame/mame -listmedia trs80
SYSTEM           MEDIA NAME       (brief)    IMAGE FILE EXTENSIONS SUPPORTED
---------------- --------------------------- -------------------------------
trs80            cassette         (cass)     .wav

SDLTRS also supports WAV-files (mono) as cassette images, so that should work too ...

Job done! That generated a flickering asterisk readout at top right, and got the command prompt back when the tape was finished, then I watched the video to find out you need to (bizarrely) type / to start the game.

Many thanks! Now I just need to get sound working...

Folly

@jimmyfromthebay

On the internet I see info of people using (binary files) :
CLOADM

You could try that.

JimmyFromTheBay

I see / doesn't work for EVERY game, so time to do some Googling. But other than sound that's the emulator figured out now, which is the hardest bit :D

Yeah, I'm quite experienced with the Dragon/Coco so CLOADM was the first thing I tried, but I'll keep it in mind for other filetypes :)

For these TRS-80 Models there is only CLOAD and SYSTEM ... no CLOADM ..

JimmyFromTheBay

@jengun Is there any significance in the fact that the asterisk readout sometimes starts with a C rather than being all asterisks? Those seem to be the games that can't be started with /.

Folly

@jimmyfromthebay

You can convert and test things on :
https://www.my-trs-80.com/cassette/

I downloaded the manual of the model 3:
If it asks for Cass ? press L or H for baudrate :
You can press enter for the memory part
then do CLOAD
then do RUN

Here you can test on the website :
Press on C-1-1 and choose Emulator (reconstructed low speed) :

Type the commands and enter :

JimmyFromTheBay

I've stumbled across the fact that sometimes you have to type a name rather than S. For example, for Meteor Mission 2, if you type METEOR the game then starts with /.

I have no idea how you work out what the name should be, because Meteor Mission 2's filename is actually METEOR2.CAS, not METEOR.CAS, but at least it's a clue... :D

@jimmyfromthebay

Never used these computers.
Just learning too.
I haven't used filenames yet.
