awesome.
*Well your PC specs are fine for OpenGL so thats gonna save time having to convert to mugen 1.0 and index.
*Secondly, RE: our discussion on discord, it appears that you are using Mugen 1.1 without any localcoord settings in your screenpack.
*You are using default mugen 640x480 resolution settings but up scaled to a stretched video resolution of 1920,1080
So in conclusion, there is no need to convert the stage to mugen 1.1 widescreen localcoord.
We will keep it as per the default and just add the floor based on its current stage.
So in conlusion, id say this is probably a 2-3hour job max:
1-1.5 x hours
New floor sprites creation
30min-1 hour/s
parallax coding implementation
30min-1 hour/s
Adjust the exiting sprite deltas/position to be in correct alignment with new floor.
(note: client wants to keep existing sprite for ledge and leave as unchanged as possible)
So all up you are looking at 3 hours labor max @ 18.00 flat rate (any extra will be no charge)
total = $54.00 (50% deposit req on acceptance of commission, 50% on completion & supply of .rar file)
