A persion who has GMP-Z003 eng showed me his tests.
M3Sakura HB OK ROM OK
R4iRTS(patched) Doesn't startup
YSMenu r4patch for M3 HB NG ROM NG
iSakuReal HB OK ROM NG
nds.m3loader.nds(g003_minigame.*) OK
TouchPod(G003) Of course, OK
TouchPod(M3DS) Doesn't startup
m3r4.dldi NG
B0 command(used as "R4 jumper check"): 0x1FC(R4 chinese)
CD command(used as "M3 region check", R4iRTS CD command is hacked for QuadBoot): 0x053(unknown)
M3Sakura 1.44: Kaura /system/sakura.eng launcher IO doesn't work (means Doesn't startup)
Conclusion: I cannot think GMP-Z003 as M3iZero. I won't recommend it to anyone because Quad-Boot doesn't work.
