Little big adventure 2 problem

espegael

The topic ya sent me is for neo geo games. LBA 2 run on msdos..

mitu

@espegael What is the error you're getting ? What files have you copied and how are you running the game ? Dosbox games have now support for running from a .conf file and I noticed some games from GOG that run through Dosbox have a .conf file also, maybe you could just custom the .conf file from the PC and adjust some paths to make it work in RetroPie.

espegael

ok so with recalbox, i created lba2.pc folder where i put all the data from gog. Then i created a dosbox.dat where it was write LBA2.EXE
finally i copy the dosbox.cfg config file and edit it

[sdl] section
change
mapperfile=lba1.map
[autoexec] section
add
imgmount d "/recalbox/share/roms/dos/lba1.pc/LBA.DAT" -t iso

and it worked

what i have to change in order that it worked on my retropie system?

mitu

@espegael Create a folder where you copy all the game's data (lba2.pc), then copy the dosbox configuration file from it (for sure it has one) to the pc folder, rename it to whatever name you'd like to have (but keep the extension). Open the configration file you just copied and then make sure the [autoexec] section (at the end) contains the proper path to the files that you copied ( in the lba2.pc folder).

espegael

OK so i start all over

I copy all the data on the lba2.pc from the gog folder (all the data but not the dosbox folder with dosbox.exe, dosbox.0.74.tar.gz, GOGDOSconfig.exe, SDL.dll, SDL_net.dll and stdout.txt)

i found 3 conf file

@echo off

lba2.EXE
exit

the path are wrong on the 2 last files? but what path do i write... im using a usb drive to put my rom on it

mitu

@espegael (moderator note) I've edited your post to be more readable, but large text files should be uploaded to somewhere like pastebin.com, they're too large for a topic.

If you have an USB to run the ROMs from it, its path will be /home/pi/RetroPie/roms. So if you copied the game in the retropie-mount/roms/pc/lba2 folder on the USB drive, the last lines (in the [autoexec] section) should be

[autoexec]
# Lines in this section will be run at startup.
@echo off
mount c /home/pi/RetroPie/roms/pc/lba2
imgmount d "/home/pi/RetroPie/roms/pc/lba2/LBA2.DAT" -t iso
c:
cls
lba2.EXE
exit

I hope this gives you an idea of how this should work. Basically retropie-mount on the USB will be replaced by /home/pi/RetroPie/roms in the file.

espegael

@mitu ok thanks for moderate me it was unreadable even for me

so i had 3 conf files
dosboxLBA2.conf
dosboxLBA2_settings.conf
dosboxLBA2_single.conf

you don't see that on my post because the first one is very long but i have these 3 conf files

in witch file i have to copy the path?
i have auto exec on the dosboxlba2setting and th dosboxlba2single

mitu

@espegael Use the 1st one and add the section with [autoexec] to it at the end.

espegael

ok i'll try it tomorrow, just a last question before leaving. Do i have to copied and renamed the conf file like you said at the begining or do i have to modify this one adding the auto exec part at the end?

mitu

@espegael Copy the file first on the USB, then open it there and add the lines with the [autoexec] section.

espegael

Ok i tried it and it disnt work... maybe i dont know with file i have to exzcute on retropie to have the game

mitu

@espegael You should be 'executing' the .conf file you created. Do you get any errors ?

espegael

@mitu i see the artictle online but i dont understand all..

http://dosonthepi.blogspot.com/2015/01/run-dos-games-in-retropie_15.html?m=1#add-dosgames

It says to create a script to aut mount the exe

mitu

@espegael You don't need to follow that page, it should work with the .conf file from the GOG installation. In the interest of science, I've experimented with it and got it to start, ~~but asks for the CD~~. Here's what I've done

Copied the game folder (from the GOG installation) in ~/RetroPie/roms/pc-data/lba2/lba2. For some reason LBA doesn't like to start from *C:* directly.
Added a lba2.conf file at ~/RetroPie/roms/pc/lba2.conf, copying the Dosbox configuration file from the GOG installation and modifying the [autoexec] section to read

[autoexec]
@echo off
mount c /home/pi/RetroPie/roms/pc-data/lba2
imgmount d "/home/pi/RetroPie/roms/pc-data/lba2/lba2/LBA2.DAT" -t iso
c:
cls
cd \LBA2
LBA2.EXE
exit

A link to the complete .conf file is here.

I start the game from the PC system, running the LBA2 entry that corresponds to the .conf file I created. It gets to the game menu, but since I don't have a keyboard, I can't say how it runs.

espegael

Ok thanks a lot! I do exactly what ypu said and it worked

I tried to play but the keypad is going wrong.. the down button is enter

2 is to go up

7 is f1

Well any idea to fix it?

espegael

I tried to play another msdos game and it worked pefectly with my jey pad so it s not my keypad the problem

Another think im french and im using my keypad on azerty mode not qwerty

mitu

@espegael said in Little big adventure 2 problem:

Well any idea to fix it?

Can't say I have, I don't play any dos games with the gamepad. Maybe you can start the DOSBOX mapper and re-map the keyboard for the game.

espegael

@mitu cant because i have to do CTRL F1 but i dont know where is the CTRL buttons

O dont know what to do.. on recalbox it was working i just add mapperfile=lba2.map

I try to do this on retrpie but it doesnot work

mitu

@espegael said in Little big adventure 2 problem:

O dont know what to do.. on recalbox it was working i just add mapperfile=lba2.map

This works if you have that file available, which I assume is not the case on RetroPie. Maybe it's generated automatically by Recalbox or by auto-configured based on something else, but here you need to use the Mapper, re-map the keyboard and save the file, which you can then reference in the .conf with mapperfile=<save_file>.

espegael

@mitu ok right it finally works. I found the CTRL and F1buttonns and configure the keymap

It works on everythink except on the number pad.. i think there is a problem with the NUM bouton. I see that the NUM led dont light when i push it.. i test on another key and its the same... my configuration configures the page up bouton and not the 8 bouton i think

The same problme appears with CAPS bouton, does raspberry support the changing of CAPS and NUM
it ligh on my computer but not in the raspberry
