As those of us who have tried playing Disgaea 3 AoD on a PS TV will know, an error message saying "this feature cannot be used" will pop up at random interval making the game literally unplayable on a PS TV.
This is due to a feature in the game called HQ "honor quotient" which gets increased by using the GPS in the VITA to keep track of how far you have traveled.
Since the PSTV does not have a GPS, this causes the error message.
However this HQ function does not get turned on until after the tutorial stages are over and this provided a chance to see if there was a variable in the game that we could find to prevent the HQ function from turning on at all.
After comparing saves and memory dumps from before and after the tutorial when the HQ function is turned on, I have now found the address the game writes to in order to turn on the HQ function.
Add the below code to your favorite cheat plugin and it will disable the HQ function completely and no more error messages will occur again when playing the game on a PS TV.
Rincheat:
#Turn off HQ function
@0x81A7DC2A @0x00 @1
GoHANmem:
#Turn off HQ function
@0x81A7DC2A @1 @00
Several caveats:
- These offsets only work on the EU PCSB00098 version of the game, I do not know if they will work on any other regions.
- If you use the code during the first chapter of the game, every time you talk to Geoffrey he will display his "what is the honor quotient" dialogue and turn back on the HQ function again, either re-enable the code or freeze the value to keep the HQ function turned off.
- After chapter 1 is finished, it appears Geoffrey will no longer force the HQ function back on again when you speak to him so after you save your game from chapter 2 on-wards you should no longer need to keep the code activated.
- Needless to say this removes the HQ function from the game completely and I do not know if there are any unforeseen consequences further in the game since I am only at chapter 2 - but I think turning off HQ is a small price to pay to disable the error message pop-ups and being able to play on the PS TV.
The only reason so much time was spent personally looking into this was because I had brought a PS TV solely to play this game. Since the game is now several years old I doubt this will be of much interest to many people, but I am sharing this so that hopefully somebody will be able to find this useful someday.
