Hacking Deluxe as RAM and memTestArm.nds

[superrab]

This is a copy of a post I made on the sosuke unofficial EZ Flash forums found here: http://ezflash.sosuke.com/viewtopic.php?p=49105#49105

Just wanted to see if anybody had any extra enlightenment:

I have an EZ Flash 4 Deluxe. Using the homebrew "memtestARM.nds" which you can get here: http://www.pineight.com/ds/ I am told that there is only 16MB of RAM in the EZ Flash 4 Deluxe.

However, the EZ Flash chinese site specifically states it has "256Mbit Psram" which is actually 32MB. GBATemp.net also seconds this in a review found here: http://gbatemp.net/index.php?showtopic=37042.

When I run the EXRAM version of QuakeDS it also only detects 16MB of RAM from my EZ4 Deluxe. Does anybody know why these homebrews do not detect the full 32MB of RAM for the EZ4 Deluxe?

Most homebrews are based off licks library and only the EZ4 deluxe has 32 MBytes of ram. Rather than mess around with stuff the author dropped the extra 16 Megs for the EZ4 support.

Ahh... that makes sense... seems like a waste though

Thanks!

I worked for quite a few hours to try and figure out a way to detect which cart was inserted without breaking others in the test, in the end it beat me though...

Doh! That would be cool if it worked out though
