Yo, this is the method i use. (credit to Dissidia)
Low Resolution/High Resolution Winmugen+ Stages:
Under [StageInfo] in the .def file, add this line: localcoord = 425,240.
Both boundleft and boundright must be substracted by 55 in order to prevent going off bounds. Example: boundleft = ??? - 55 = The new number.
MUGEN 1.0+ coded 320,240 stages:
Under [StageInfo] in the .def file, add this line: localcoord = 425,240
Both boundleft and boundright must be substracted by 55 in order to prevent going off bounds. Example: boundleft = ??? - 55 = The new number.
MUGEN 1.0+ coded 640,480 stages:
Under [StageInfo] in the .def file, change the line localcoord = 640,480 to localcoord = 850,480
Both boundleft and boundright must be substracted by 105 in order to prevent going off bounds. Example: boundleft = ??? - 105 = The new number.
