okay so the games started working when I used the m3u from the translated version. Maybe there was something screwy with the other game files I tried or they struggled to work right unless I use an m3u. sigh now if only some of the other cores would recognise the m3u files existing >< that's a topic for another post though

@JimmyFromTheBay said in Does anything run Sex Bomb Bunny on MSX?:

@Folly Ooh, that's interesting - the old unmodified disk DOES work fine now.

Aha, so it does stick on your openmsx install, good to know.

(But it's still flush to the bottom.)

Also on my end it's a bit to the bottom, not much we can do about it but it works !

@duglor In the RetroPie docs you will find all the necessary info about the bios files of openmsx: https://retropie.org.uk/docs/MSX/

The only you have to do is to choose the emulator from the runcommand menu.

@mitu ah okay, so there's an improvised numberpad on there. A bit of a slanty one but that will do.

@windg Thanks, but THAT game is actually a translation of XZR II and Exile 2 is actually XZR III. XZR I was not translated into English and is only on the PC-88 and MSX.

@barbudreadmon
don't worry about that, thanks

@2Play Yeah - I will sort this.

@gomisensei Yes, I'm aware of that. What I'm concerned with is getting it working. It doesn't run in lr-bluemsx, lr-fmsx doesn't run anything at all, lr-fbneomsx doesn't support MSX2 and lr-mess runs it but neither keyboard nor joystick responds.

@jimmyfromthebay

Aha, MAGIC, that's nice to hear !

Btw., what is the md5sum of your "Jet Set Willy (1984)(Software Projects).dsk" ?
Perhaps you have a different file than me, if so, the patch probably will not work because of that.

It would be nice to know the cause.

I suspect the cause was GitHub. I can never remember which method of downloading files from GitHub pages gets you the real file, and which way gets you a broken useless one just pretending to be it.

Never mind.

I don’t know how to mark this post as [solved], but I’ll try to make a summary of the lessons learned here anyway:

lr-fbneo-msx needs all MSX BIOS files in on pack named msx.zip in /home/pi/RetroPie/roms/msx/msx.zip lr-fbneo-msx needs ROM files to be zipped and verified against DAT checksums (the filename and CRC must match) MSX ROMs that are downloaded together with lr-fmsx does not work with lr-fbneo-msx (CRC are different for all files); you have to find the right BIOS files elsewhere. I still unable to load ROMs with lr-fmsx (however lr-bluemsx is a good alternative so far) In lr-bluemsx you can use the keyboard in MSX if you add a input_enable_hotkey in /opt/retropie/configs/all/retroarch.cfg or /opt/retropie/configs/msx/retroarch.cfg:
input_enable_hotkey = "tab"
Normally you would press "F1", when enabled you have to press "TAB + F1"

Thank you @mitu and @Folly for your help!
Happy MSXing

@TPR

Did it work ?

@fryguy1 Please don't post links to ROMs or ROM sites.
Not sure why this reply was needed, since @Folly already provided a solution in one of their earlier posts, but I guess the more the merrier.

I do confirm, all systems are there to scrape. Very cool.

@mitu Ah I see! That makes a lot of sense. I've got it now thanks! Just need to figure out what buttons I've got and it's all dandy. Although I guess I also need to map some of them so I can still exit retroarch.

@folly Thinking about it, is it possible it might work on other cores? Is it a functionality all the lr cores share?
