What you need:
1) Photo Shop
2) Alienskin Blowup Plugin (best blowup tool available)
3) Knowledge on how to make a script in Photo Shop so that you can apply the filter to all the sprites quickly.
How you do it:
1) Use Fighter Factory to export the sprites from the SFF file (Sprites/Export sprites/SPR Maker)
2) Open a sprite and in photo shop record the script to...
b. Set color to RBG
c. Open AlienSkin Blow Up filter
d. Resize to 200%
e. Close Alien Skin Plugin
f. Set color to index and apply the mugen act pallet.
d. Save and close
e. End script and run script on all shared palette sprites.
3) Open the text file created by the SPR Maker in step 1 and double all the sprite possition numbers. I use Excel for this step to speed up the process.
4) Rebuild SFF file quickly by using sprmaker.exe that comes with mugen.
Done... now the other parts...
5) Use Kong's Double CLSN tool (downloadable on IMT website) to quickly adjust the Colision Boxes in the AIR file.
6) Open the char in fighter factory and find the code in the CNS file for each of the explodes and double the size. You'll probably have to change the possition of projectiles, helpers and hitsparks too.
