HOW TO COMPILE AND RUN
The instructions here refer to compiling the example from the command line. For Microsoft Windows users we suggest using UGBASIC-IDE, which allows you to compile the example with just one click.
ATARI 400/800 family
In order to compile and run the example, you need to have the Altirra emulator, and in particular that the altirra executable is accessible.
Then, type this command on the command line:
# Linux ugbc.atari stage2.bas -o example.xex altirra example.xex # Windows ugbc.atari.exe stage2.bas -o example.xex altirra example.xex
ATARI 600XL/800XL/1200XL/XG(SE) family
In order to compile and run the example, you need to have the Altirra emulator, and in particular that the altirra executable is accessible.
Then, type this command on the command line:
# Linux ugbc.atarixl stage2.bas -o example.xex altirra example.xex # Windows ugbc.atarixl.exe stage2.bas -o example.xex altirra example.xex
Commodore 64
In order to compile and run the example, you need to have the VICE emulator, and in particular that the x64sc executable is accessible.
Then, type this command on the command line:

Commodore PLUS/4
Using YAPE
In order to run the example, you need to have the YAPE emulator. In particular that the yape executable is accessible.
Then, type this command on the command line:
# Linux ugbc.plus4 stage2.bas -o example.prg yape example.prg # Windows ugbc.plus4.exe stage2.bas -o example.prg yape example.prg
Using VICE
In order to run the example, you need to have the VICE emulator. In particular that the xplus4 executable is accessible.
Then, type this command on the command line:
# Linux ugbc.plus4 stage2.bas -o example.prg xplus4 example.prg # Windows ugbc.plus4.exe stage2.bas -o example.prg xplus4 example.prg
Dragon 32
In order to compile and run the example, you need to have the XROAR emulator, and in particular that the xroar executable is accessible.
Then, type this command on the command line:
# Linux ugbc.d32 stage2.bas -o example.bin xroar -rompath (your rom path) example.bin # Windows ugbc.d32.exe stage2.bas -o example.bin xroar.exe -rompath (your rom path) example.bin
Dragon 64
In order to compile and run the example, you need to have the XROAR emulator, and in particular that the xroar executable is accessible.
Then, type this command on the command line:
# Linux ugbc.d64 stage2.bas -o example.bin xroar -rompath (your rom path) example.bin # Windows ugbc.d64.exe stage2.bas -o example.bin xroar.exe -rompath (your rom path) example.bin
PC128 Olivetti Prodest
In order to compile and run the example, you need to have the DCMOTO emulator, and in particular that the dcmoto executable is accessible.
Then, type this command on the command line and on the emulator:
# Linux ugbc.pc128op stage2.bas -o example.k7 dcmoto (choose BASIC 128) CLEAR,&H2FFF: LOADM"CASS:",R: EXEC # Windows ugbc.pc128op.exe stage2.bas -o example.k7 dcmoto (choose example.k7) (choose BASIC 128) CLEAR,&H2FFF: LOADM"CASS:",R: EXEC
Thomson MO5
In order to compile and run the example, you need to have the DCMOTO emulator, and in particular that the dcmoto executable is accessible.
Then, type this command on the command line and on the emulator:
# Linux ugbc.pc128op stage2.bas -o example.k7 dcmoto (choose BASIC 128) CLEAR,&H2FFF: LOADM"CASS:",R: EXEC # Windows ugbc.pc128op.exe stage2.bas -o example.k7 dcmoto (choose example.k7) (choose BASIC 128) CLEAR,&H2FFF: LOADM"CASS:",R: EXEC
Commodore VIC-20
In order to compile and run the example, you need to have the VICE emulator, and in particular that the xvic executable is accessible.
Then, type this command on the command line:
# Linux ugbc.vic20 stage2.bas -o example.prg xvic --memory 24k example.prg # Windows ugbc.vic20.exe stage2.bas -o example.prg xvic --memory 24k example.prg
ZX Spectrum

Then, type this command on the command line:
# Linux ugbc.zx stage2.bas -o example.tap Speccy example.tap # Windows ugbc.zx.exe stage2.bas -o example.tap Speccy example.tap
MSX
In order to compile and run the example, you need to have the openMsx or the BlueMSX emulator, and in particular that its executable is accessible.
Then, type this command on the command line:
openMSX
# Linux ugbc.msx1 stage2.bas -o example.rom openmsx -cart example.rom # Windows ugbc.msx1.exe stage2.bas -o example.rom openmsx -cart example.rom
