It's one of the possibility. Did you read the read me file?Your words?
I showed my "system". And they still have a "black screen" in most "activities"! I won't say anything about opening the "usage book" - it just freezes the game! And all that can be done after that is to "remove the task" through the task manager!
So your "excuse" about the "old age of the system" has no basis in fact! Rather, you need to understand which "codecs" YOU are using, and whether the USER has them in the system! After all, it may be that in pursuit of "compression efficiency" they used some kind of "specific" and rather rare codec that most users DO NOT have - that's why we get what we get - a black screen or a game freeze!
Still you can tell me this, like a normal person you know.. not like someone with anger management problem..
