Add the "GHOST DATA CANNOT BE SAVED" element to single player gameplay screens other than time trial:

Code:

# inject at 808584d8 (PAL)
# inject at 80836a48 (NTSC-U)
# inject at 80857b44 (NTSC-J)
# inject at 80846898 (NTSC-K)

cmpwi r3, 0xc # grand prix
beq invert

cmpwi r3, 0xe # 1 player offline vs
beq invert

cmpwi r3, 0x12 # 1 player battle
beq invert

cmpwi r3, 0x40 # 1 player ww/regional vs

Extend the setTextSrc method to load text from an arbitrary string instead of a bmg, if the argument in r4 is null:

# inject at 805cd610 (NTSC-J)
# inject at 805bbcf4 (NTSC-K)

Make the element visible, and set its value to the current speed:

Cannot overstate how useful this is going to be. Finally dolphin users will have a nice looking som, and this'll also help distributions that do not want to use CT-code. Amazing job and already a contender for code of the year in...January.

This!

2021 Code of the Year

[Jeffy/Wrath]

OMG this is great

[stebler]

The code has been updated with correct right-alignment instead of padding zeros, and some slight latency improvements.

[Optllizer]

Really Nice Code. Will is be possible to change the color of it ?

[stebler]

Yes, you can do this by replacing 00010030 with 000100xx where xx is 00 for gray, 01 for red, 02 for white, etc. You can find the full color list here.

Video of the code in action

[Again]

NTSC-K shows a bunch of blocks , just letting know

I updated a new version that hopefully fixes the bug (the code was using snprintf instead of swprintf), can you test it?
