For now (until the changes are pushed upstream) you can use this fork of Genesis-Plus-GX-Expanded-Rom-Size to compile from source.
Simply download into "/home/$USER/RetroPie-Setup/scriptmodules/libretrocores"
wget https://raw.githubusercontent.com/RapidEdwin08/Genesis-Plus-GX-Expanded-Rom-Size/master/builds/lr-genesis-plus-gx-EX.sh -P ~/RetroPie-Setup/scriptmodules/libretrocores/
Then use RetroPie-Setup like normal to install from Experimental Section.
This will install an Additional Core [lr-genesis-plus-gx-EX] that you can use just for Paprium and SegaChannelRevival.

This worked perfectly fine for me. Thank you.

@TPR will there be any updates for the genesis plus gx ex? Where do we follow this updates?

I have no idea. I didn't make the update. I just installed what was already posted here. This is how I did the process...

I went to this URL (that was posted from the wget instructions above)
https://raw.githubusercontent.com/RapidEdwin08/Genesis-Plus-GX-Expanded-Rom-Size/master/builds/lr-genesis-plus-gx-EX.sh

I copy/pasted that text into coderunner, saved it as a .sh file and added that .sh file to my scriptmodules folder.

Ran the RetroPie Setup, installed EX from the experimental section, and BOOM! Everything worked just fine.

Took me about 3-5 minutes to get it all working.

Hope that helps!

@TPR yeah i have it installed, are you getting crashed or kicked out at all? I get kicked on at the end of level 2 everytime, any problems on your side? Thats why i was asking if their gonna update it to fix some of this issues...

Nope. Works perfectly fine for me. No issues at all.

Just played past level 2 into level 3 and no issues whatsoever. There is no update needed.

I literally just posted above exactly what process I went through. I'm on a Pi 5. I would imagine that anything lower than that may have issues. And if you're on a Pi 4 or lower, you probably shouldn't be.

FBNeo will support this game soon.

nestor1924

@barbudreadmon thats nice! This will make it more playable for me since im having issues with megadrive emulator

I've played through at least 3-4 levels in the game now with zero issues. Not a single glitch or anything. I don't think the problem is the emulator core.

nestor1924

@TPR yeah im guessing your right... but already give up with this issue and hoping i can finally fully play the game on when fba version its releseased...

FBNeo used genplus-gx's paprium implementation as a starting point for FBNeo's implementation, so i can tell there are problems with genplus-gx's implementation, one of them was explained on FBNeo's forum.
I'm also not entirely sure how well this genplus-gx implementation support savestates and savestate-based features (runahead, netplay, rewind, ...)

@roslof Thanks, I've tried so many things, most of the time when selecting a character it goes back to the game selection, sometimes before. Now the only problem is when I reset from the minigame, I hear the background noise. MP3s are fine, but that noise is unnerving! I have a PI3B+.

barbudreadmon

A bit of warning about paprium, it can end up using quite a lot of ram : everytime it needs to play a mp3, it'll buffer it into ram after decoding it, for a total of 2.1GB if it plays all 50 tracks. If you don't have enough free ram, best case scenario it won't play the song, worst case your device might become unstable.

nestor1924

@barbudreadmon may that be the reason i cant make it pass level 2? I have a raspberry pi 3b+

barbudreadmon

@nestor1924 Linux will kill the process with the highest memory usage if it ever run out of ram, it is extremely likely that this is what's happening to you.

One possible workaround would be to add a swap file to your os : https://linuxize.com/post/create-a-linux-swap-file/
Keep in mind this will be "ram on the sd card", which might wear out your sd card prematurely.

Another possible workaround would be to play the game without sound by removing the mp3s.

nestor1924

@barbudreadmon I think for now ill wait and see if the Fbn versiob works for me when its released, if not ill get the Pi5, ill try the no MP3 to see if it works.

FBNeo, instead of loading mp3s "on demand" like that genplus-gx hack does, loads everything at boot to prevent the "hanging" issue mentioned on our forum. To speed-up loading it was also decided to convert those mp3s to our samples format (meaning a zip file containing .wav). The total requirement for running this game with samples will be around 2.5GB ram (minus 2.1GB if you remove the samples).
