had a similar error in the past was kinda the same after reading some info and learning more it was due to some simple problems
First problem number of explods
Since people use default config they tend to run into those problems after checking the txt on the char i learned that was due to explods and needed a higher ammount then the one i used so i changed to this
;Maximum number of explods allowed in total. Note that hitsparks
;also count as explods.
;Set to a lower number to save memory (minimum 8).
ExplodMax = 5800
after that no errors.
Second problem that gives the same error SpriteDecompressionBufferSize
This is an error from modern mugen only and is the amount of ram used to decompression some characters need higher then default and give a similar error,this is the ammount i use
;Size of sprite decompression buffer in KB. Increasing this number may help
;if you experience slow performance when there are many sprites and/or large
;sprites shown over a short period of time.
;Minimum 256 for acceptable performance.
;If you set this too large you may also experience performance degredation.
SpriteDecompressionBufferSize = 262144
It will use 256 Mb of ram so everything will work better and no errors
The third problem
using a 1.1 char on 1.0 sadly most of those chars take advantages of certain stuff undocumented but the error is similar,the features are normally more wavchannels and increased helpermax
This was required for a touhou character exclusive for 1.1
;Maximum number of helpers allowed in total.
;Set to a lower number to save memory (minimum 4, maximum 56).
HelperMax = 300
;Number of voice channels to use.
WavChannels = 128
normally you need less but that character used more wavchannels and more helpermax so was kinda forced
Using all those settings is safe normally requirements will increase but aren't something outside of this world (i use them on my projects and are more stable then normal mugen games that crash afetr some minutes)
