like this: Of course in actual code you need to transfer temp to ARM9 using fifo or IPC.

If you are talking about gbalzss, I use my modified(because original gbalzss.c isn't working) version of gbalzss to compress.

You can use "gbalzssrawstdio -c <bin >bin.lzs". If you want vramsafem, use -cv instead

nds/arm9/videoGL.h
- sassert(count != NULL,"glCallList received a display list of size 0");
+ sassert(count != 0,"glCallList received a display list of size 0");
will fix that because count is u32...

#Awww possibly wrong section (should go to libnds) very sorry...

Today I disassembled MoonShell2.10 to compare FAT_LinkFreeCluster()
and_FAT_fat_linkFreeCluster().
Both "modified gba_nds_fat" and libfat had:
---
if ((curLink >= CLUSTER_FIRST) && (curLink <= fatLastCluster))
{
return curLink; // Return the current link - don't allocate a new one
}
---
But ...

Thank you for fixing.

If

backlight & ( 1 << 3 ) == Wall power ( 0 = no, 1 = Yes )
battery = 32768 - green light + wall power
battery = 32769 - low power, but recharging.

is meant, I think
battery += backlight & (1<<3)<<12
should be changed to
battery += (backlight & (1<<3))<<12

I have checked libnds-src to figure out that getBatteryLevel is a FIFO function.
Then I see ARM7 code:
battery = readPowerManagement(PM_BATTERY_REG) & 1;
backlight = readPowerManagement(PM_BACKLIGHT_LEVEL);
if (backlight & (1<<6)) battery += backlight & (1<<3)<<12;
