[iOS] [C64.emu] crashes on startup #111

Closed ck16 closed 2 years ago

ck16 commented 6 years ago

Hi @Rakashazi,

I edited line 579 of imagine/src/base/iphone/iPhone.mm as suggested and managed to compile the emulator.

When I start the emulator I get a black screen, then it quits after 1 or 2 seconds.

I tried on an iPhone 7 Plus, iPhone X and iPad Pro 12.9" and get the same result on all 3 devices.

Also is there any plan to support the newer screen modes on iOS devices and to fix the rotation bug of the UI?

Thanks heaps!

Cheers, ck16

I forgot to add that all the other emulators run fine.

Rakashazi commented 6 years ago

It's probably related to the dynamic library loading so I'll have to do some further testing. As for the updated screen modes I'll look into those as well.

Hi @Rakashazi,

I just tried the latest version of the code and noticed C64.emu still quits straight after launching. Not sure if you managed to look into the dynamic library loading or not.

Thanks heaps for your help!

Cheers, ck16

Hi @Rakashazi / @yoshisuga,

Did either of you manage to find the cause of the C64.emu app crashing on startup?

Cheers, ck16

yoshisuga commented 5 years ago

I haven’t had the chance to trace the root of the cause - it’s hard to track down for me because of my unfamiliarity with the development environment and dealing with precompiled sources. I can hit a breakpoint in Xcode, for example, but I wouldn’t be able to tell where in the core source the error occurred

Hi @Rakashazi / @yoshisuga,

Was there any update to this issue?
