you need original dosbox with munt patch or dosbox staging (develop version with already integrated MT32)
and the MT32 roms
grab the develop-version of staging which already integrated MT32 support:
i've uploaded the current development version (im also using) to:
https://easyupload.io/nbo5r5create following pathes
C:\temp\mt15_tests\romfiles <- fill that with the mame rom files: seach for "mame mt32 rom" you should find a mt32.zip and a cm32l.zip (extract copy all .rom/.bin into this folder without sub-folder)
C:\temp\mt15_tests\stunts11 <- your stunts 1.1 copy AND unpacked game.exe from the restunts projects (also attached)
C:\temp\mt15_tests\dosbox <- put in here the dosbox staging alpha files AND the attached dosbox.conf
then run the dosbox exe - stunts should start automaticly
relevant lines in the dosbox.conf are marked with "# !!Daniel3D!!" but should work out of the box if you can use the pathes as stated above
then you can check if
reMT15/10/MT15.DRV sounds/behaves the same as the stunts 1.0 MT15.DRV (org/10)
reMT15/11/MT15.DRV sounds/behaves the same as the stunts 1.1 MT15.DRV (org/11)
used with stunts 1.1
attach-info:
game.exe from the restunts project - copy into the stunts11 folder
dosbox.conf - copy into the dosbox folder
reMT15.7z - contains my 1.0 and 1.1 version of the Stunts MT15.drv
org.7z - contains the original 1.0 and 1.1 version of the Stunts MT15.drv
