BeebEm Alpha Fork with SID and PAULA sound

Post by dominicbeesley » Sun Dec 01, 2019 11:45 pm

I've been experimenting with emulators and had a go at implementing the SID and Paula sound cards in BeebEm. I've added an alpha release on GitHub at https://github.com/dominicbeesley/beebe ... ossy-alpha

The installer contains some sample disc images for SID and Paula demos. (For Paula the files are quite large and slow to load from DFS so I've included an .adl file too - OSGBPB is _slow_ in DFS!).

If you want to try out more Paula tunes then you should be able to replace the files in the M directory with Amiga ProTracker files of your choice - most seem to play well on the included modplayer - let me know any you find that don't and I'll look to update the player.

The included SID files are a bit hit and miss, some don't work but most do and sound pretty good. Playlist1.ssd and Playlist2.ssd are good starting points

Thanks to Chrisn for helping me get this working and allowing me to do a pre-release.

The usual caveats for Alpha software apply

Is there genuinely no interest or have I done something daft? So far it looks like nobody has tried the download or have I made a balls of publishing it on GitHub?

Oh, I downloaded, installed and ran the emu this morning - listened to all the Amiga mods was absolutely amazed with the quality! I'll definitely be needing a hardware equivalent of the Paula board at some point!! Great work Dom!

Tomorrow I must try your 1MPaula project on the Beeb 1MHz Bus FPGA board:

Can you give me the three-line summary of the best available demo for this?

I will be, just working today and had a meeting this evening, so no Beeb time.

Thanks Arcadian, my two downloads must have been counted as one then! Glad you liked it. If you want to make more then you can try any of the 4 channel "mod" files that are less than 400K from https://modarchive.org/index.php?reques ... ery=105534 download the file and get them into the M directory with adfs explorer or similar

Hoglet, the modplayer on the Paula.ssd or Paula.adl discs (on Git for Paula fpga and BeebEm) is the only thing I've written. However, as above any of the mod files above should work. I could post up the code for the player - it should be easy enough to integrate it into a larger demo

Also, I've attached another .adl with a few larger mod files

Aw, thanks for posting the extra disc - have had the three new tracks playing for the past half hour - really enjoyed them. I'm super busy with events for the next week so won't have time to put any mods together for at least a week but if you're taking requests I'd love to hear a disc of the Pinball Dreams tracks! ;)

Thanks, they sound great! I'm surprised I didn't recognise most of the tracks on the Pinball Dreams selection, I probably spent more time on Fantasies and Illusions.

Wow - very impressive!

I created a quick disc containing some of my favourite mods from back in the day, written by Dr Awesome.

I've updated this a little. There are now new disc images (attached) the main difference is a new menu system and slightly updated hardware detect code and it's all shifted up in memory to allow page to go up to &2000 so ADFS can be used for faster loading.

I've also made a B-em version of the emulation here https://github.com/dominicbeesley/b-em/ ... st-release there's a pre-built windows .zip here which contains a scsi hard drive with a load of tunes on. For non windows users it should work though I've not had a chance to test this properly on Linux.

You should be able to unzip and run b-em.exe. You will then need to:

Enable paula:

Code: Select all

Settings->Sound->Paula
Enable ADFS:

Code: Select all

Model->BBC B w/1770

Code: Select all

ROMS->[empty slot]->LOAD->ADFS130
Enable SCSI:

Code: Select all

Disc->SCSI Hard Disc
Reset

You should then be able to run mod menu in the $.MODS.ONE directory

paula_2.png
paula_3.png

The SCSI disc in the release can also be used in BeebEm in the usual way

I'd be very interested to hear any feedback (positive or negative) on the b-em download, especially if anyone has managed to run it on Linux, either here or by PM.

Thanks

Thanks for the effort, I love having another emulator to compare and test.
I have tacked the building process under Linux (Lubuntu 16.04), it works. My first impression is that of an enhanced GUI and a little slower than b-em 2.2 but I haven't still measured the speed so take it with salt. The building process has been summarily logged in the attached log file.

Thanks Nicola, that is very helpful!

I've made a change to the source on git hub to get rid of those types, I think the rest (getting allegro) is covered in the general build instructions.

Did you try the "Paula" sound - did it work ok?

Thanks
