It would be nice if you could watch at the memory address and tell gens to freeze when the value is equal to something. i.e. : I'm looking for information about Shining Force 2, and I found out that when a memory address is 53, i will do a double hit. It would be nice to be able to break on that value, and then attack to do a double hit. I hope it is clear enough for you to understand.

That might not be helpful because the memory addess may only be 53 for one frame. And when you unpause gens, it will be the frame AFTER the one you wished to pause on... However I suppose it will be helpful because then you can tell that it is on a particular framenumber (11921 for example) then simply use framesearch to search for the frame before it...

Well it is useful, depends on how you make it work, I don't know assembly, but I know that when the value equals 53 if I press A and then attack, I do a double-hit, but the RNG change value a couple of time, but always in the same order, so I can pretend that when the value is 53 and I press A, i'll do a double-hit.

You're not quite understanding what im pointing out. When gens finds value 53. It pauses. Then when you unpause and press A, it won't be 53 anymore.. because it was 53 when it paused, when you try to press A it'll be 54.

okay, well I found out that it would be easy to just open two emulator (i have to screen) on my run, i make a savestate, I find the frame number for that value, I'm going to the frame before, and then i press A it will be the same.

DDRKhat: Most probably you would search for the value that gives you desired result if you do an action just after it shows up. That would be how you found it, anyway. Even if it works like you say, it would be darned easy to load state and frame advance until one frame before the frame that just showed up.

Yup that would be really easy. I'll take a look too in the code to see if I can modify the emulator to do some testing memory value. It might be possible to do something that would test 10,000 with a frame interval of try+1 each test, and looking for memory address, and outputting result in a file (RAM watch and frame number). That would be easy to find the result you want, like doing the most damage in an rpg. I'll see, if it works well, it would be a great tool for tasing.

If you're on Linux, I'm using a robot that does something fairly similar. Let me know and I'll show you how to use it. Unfortunately the code isn't cross-platform, but you may be able to successfully bug Upthorn (to work in win32) or use VMware (to run Linux).

That shouldn't be too hard to implement with the current Ram Search, but it may be a while, as I don't want to add any big new features before Gens 10.

gens 10 ? so you're preparing a bigger new features list for an upcoming release ? by any chance, is "taking gens+ as a source basis" in this list ? that way we could have a (primary, better than nothing) sms/gg support, since the meka upgrading project is on an unlimited hiatus :/ any way, thanks for the maintaining of the gens project !

Well i'll see, anyway I don't have a lot of skill with C++, unless gens is written in another language. But I have enough programming skill to be able to modify it. Anyway I'll give a try, if you would like to send me the code you made for linux, it may be useful to translate part of code.
