Heh. I played Cave Story for the first time not too long ago and it's amazing. Finding an exploit for it makes it even better.

This is a dead thread. Youre not going to get a buffer overflow from editing unsigned data from a text file anyway. And if it did crash, that doesn't mean an exploit is possible, it means it kept the overflow from happening which was intended.
Since this thread was seemingly resurrected, I might as well bring up the results I had with this. No, an exploit using this entrypoint is not possible. Maaaaybe someway or somewhere else, but not here.
I ran through and debugged the code, watching exactly what it does, and a buffer overflow does indeed occur. In the code, it specifically checks for a null terminating character, but never verifies the date string's length. This is all great, but the overflow does not occur within an exploitable area of memory (that I am aware of).
Perhaps I will eventually continue to search for entrypoints within this game, as this was a fun little exercise for me at the time, but as it stands, this isnt an exploitable entrypoint. Sorry guys.

If your internet speeds are fast enough. Streaming 4k takes alot. I used to only have 20mb sec, and 4k struggled. Now I have 300mb sec and 4k plays fine.+1 -

I think Game streaming should work like this.... Local Hardware able the run the game fine, game engine and common assets stored locally, all FMV and music and textures could be streaming+1 -

also @BigOnYa im making some progress on my gdevelop project, implemented various mechanics -

Or free government supplied high speed internet be nice also. Like Obama care. Xdqwerty that's cool, its time consuming but rewarding once done or playable, to see what you've made from scratch. Animations take forever, but worth it.+1

and the visual aspect of the game is quite crude (the sprite that looks best is that of the protagonist just because he is a stickman with sunglasses) -

BigOnYa:
There is a bullets behaviour you assign to your character, that makes the code easier, under "behaviours"

Xdqwerty:
i meant that when the character is pointing to the right, the bullets spawn where they should, but when he is on the right, they move to the right but the spawn point is incorrect

BigOnYa:
Itch.io has lots of free assets also. Under the bullets behavior tab, there is a "rotate bullets" option, can try that. Or in the code can try
- fire bullet Player.X(PlayerDirection) -

That's cool tho, I'm proud of you going back to it, not giving up. It is difficult at first to learn, but fun once you get the hang of it. I think I've watched every tutorial video there is, but I still struggle sometimes to get stuff to work right. But gotta keep trying dif things, and eventually you will get it right.+1
