White screen on loading battle map - Fire Emblem Path of Radiance [PAL]

[GoogleCodeExporter]

What steps will reproduce the problem?

Start and play Fire Emblem up until you'd expect a battle map to be loaded 
(usually directly after the Chapter screens). The game fails to load the battle 
map and gets stuck on a white screen. Happens intermittently, sometimes the 
screen will pass without issue.

What is the expected output? What do you see instead?

Expected output is the battle map/scenario being loaded and playing. White 
screen hang is the actual outcome 70% of the time.

What revision of Nintendont are you using? On what system Wii/Wii U?

I have noted this issue in Nintendont 2.157, 2.155, 2.152 and 2.120. Crash/Hang 
happens with equal chance across all versions. 

System is a Wii - system menu 4.3E (Europe). 

Please provide any additional information below.

The iso is being launched from a USB. I have tried several iso versions (both 
from my own disc and from various internet sources). 

Memory Card emulation is on, with a block size of 251. No multi-card. 

Nintendont is being launched directly from the Homebrew Channel.

Here is what I believe to be the relevant extract from the log file. The full 
file is attached.

Also tested with the NTSC version of Fire Emblem, same issue. 

Forgot to mention I'm using a USB Verbatim Hard Drive with a sector size of 
512.

Changing emulated memcard size to 59 blocks will get you past the first chapter 
loading screen hang (first chapter, not prologue hang), but will again hang on 
chapter 2 even with the reduced memcard size.

Confirmed on 2.162.  Also happens when playing from SD.

Getting the same problem here... when started to play for the first time, I was 
able to go even into chapter 2, but the memcard emulation was turned off. Since 
I turned it on, the same problem happens, even after the memcard emulation was 
once disabled again.

Wii 4.3U, Nintendont Version 2.162, wiimote with classic controler, loading 
direct from homebrew channel.
