This is a sub-page of Wario Land 4.
Partial source code for the game was found in the files of the July 2020 leaks at the path d1\routefree\bbgames\depot\wario4land_gba_ique and with a small amount of work, can be built into a debug-enabled ROM. The debug mode which is present in retail is enabled here by default, in addition to many more options including a full debug menu.
An xdelta patch to enable these features can be found here:

Steps to Build#
For reference, the steps that were taken to build the ROM are:
Set up a WinXP VM: Get a copy of the gbasdk zip: Install GNUPro021206.zip, then copy the bin, include, and lib folders to: C:/agb
Edit GNUmakefiles:
Remove -mthumb from all GNUmakefiles' ASFLAGS and CFLAGS. Also, remove all occurrences of -DCHINA=1 and change CHINA = 1 to CHINA = 0
Edit crt0.s:
Remove "_zh" from: .INCLUDE "crt0Include_zh.s"
Restore the following files:
wario4land_gba_ique\src\gmap\Attic\Save_SramAccess_debug.o,v
wario4land_gba_ique\src\gmap\Attic\Save_SramAccess_release.o,v
Once restored place them at: wario4land_gba_ique\src\gmap\
Fix for WriteSramEx:
Copy AgbSram.h and AgbSramFast.h from: netcard\gba\sw\gba\include\nintendo\backup to: C:\agb\include Then add extern u32 WriteSramEx(u8src, u8 dst, u32 size) ; to sram.h (before the last #endif).
Copy all *.a files from: netcard\gba\sw\gba\lib\nintendo to: C:\agb\lib
Building: Refer to the readme.txt in the src directory. Full debug features can be enabled by setting TITLE_DEBUG_MODE TRUE as well as uncommenting #define SEL_DEBUG
