This guide aims to define configuration on DOSBox for Lotus III.

Most developed machine in the begining of 90s was PC computers with 80386 microprocessors.

Game is created in the begining of 90s to use most developed audio and video technology which were Sound Blaster 16 and VGA 256 colour with 320x240 screen resolution.

Below configuration is enough for the game :

"Lotus3.conf" file content :

[START OF FILE]

[sdl] fullscreen=false #if you want to play game in full screen, you can turn it to "true" fulldouble=false fullresolution=original #your desktop screen resolution windowresolution=1024x768 #i like to play game in a window with good visibility. This i my choice. You can alter it as you like" output=openglnb #Other selections were blury as output. This is best i find for clear visibility in screen autolock=true sensitivity=100 waitonerror=true priority=higher,normal mapperfile=mapper.txt usescancodes=true

[mixer] nosound=false #we use sound card. So, set it to "false" rate=44100 blocksize=1024 prebuffer=20

[midi] mpu401=none #if you like to use something like Roland MT-32. Set this to "intelligent" mididevice=none #if you like to use mpu401 device "win32" is best option midiconfig=0

[sblaster] sbtype=sb16 #Best sound card in that time. You can choose better cards, but there will be no difference. Actually every Soundblaster soundcard types sounds the same. This is my choice. sbbase=220 irq=7 dma=1 hdma=5 sbmixer=true oplmode=auto oplemu=default oplrate=44100

Shortcut for the game to run DOSBox with Lotus3.conf (Game configuration file) : "C:\Program Files (x86)\DOSBox-0.74-3\DOSBox.exe" -conf "C:\Program Files (x86)\DOSBox-0.74-3\lotus3.conf"
