[Help for questions] For version 5, there is a problem with the GBA emulator (vBag1.25)

_____ has recently successfully cracked the phone and has become interested in a wider range of GBA games. I fumbled and downloaded the GBA emulator, and then downloaded the larger GBA games according to the traffic limit, because I wanted to try something new...
_____ I followed the steps, unzipped the game, and placed it in the E drive-data-others-vBag folder. I opened the game and it ran normally. There was a picture (although it was a little small) and music (can't turn it off and turn down the sound?). When I got to the menu page, I couldn't do anything because I didn't see the virtual keyboard and the touch screen didn't respond... Sigh - I finally spent a lot of money to download it, all the preparations were done, and the game was able to run. However, because of operational problems, all my previous efforts were wasted... I'm at this point and I can't play...
_____ Does anyone passing by know how to solve this problem? Is that GBA emulator not suitable for version 5? I hope someone can help me solve the problem. I really want to try the fun of GBA games.
