Unable to use IR port in Chee-Chai Alien #48

Open Xukkorz opened 2 years ago

Xukkorz commented 2 years ago

Game Chee-Chai Alien requires you to hold up the IR port to incandescent bulbs to activate certain parts of the game. IR port on Pocket is either not sensitive enough or does not respond to the same wavelengths. Tested on same bulb as on original hardware and where it worked on gbc, it did not work on pocket. On going to light sensing section of game there was a blink where it looked like it saw some light, but then it cut out to nothing.

Game is GBC only and does load, just unable to actually use IR port with game. https://en.wikipedia.org/wiki/Chee-Chai_Alien

Edit: Forgot to mention, using an original cart.

I haven't been able to get the IR port working as well. See #41 as well :(

How well does Chee-Chai Alien work without that "spectrum communicator" attachment? The attachment is shaped to clip onto a Game Boy Color.

Xukkorz commented 2 years ago

The spectrum communicator is just a big orange piece of plastic that doesn't even cover the IR port. Not sure it does anything other than possibly reflect a bit more light down at the sensor. Looks cool though.

It seemed to be working for me when using a .pocket conversion and pointing a remote control at it. The IR response reflected my button presses, although they maybe were weaker than the real hardware.

Xukkorz commented 2 years ago

It kinda works but then cuts out I can try and film a video but it seems like it just cuts out.

JoseJX commented 2 years ago

Maybe the IR sensor isn't as sensitive to the light bulb's IR frequency? I wasn't using a light bulb, just a regular Vizio remote control. I unfortunately don't have original hardware to test this on though, I've only got my DMG here.

Xukkorz commented 2 years ago

Possibly, gbc was a very different response but it was like it got ghost input on Pocket then didn't do anything more. I'll try to film it and post the difference in the morning.

Any better on 1.1 beta?

Xukkorz commented 2 years ago

No change in behavior.
