thought the Everdrive didn't have RTC?

Okay bought the The GB USB 64M Smart Card from Retro Towers, wasn't cheap but what can you do, at least i know it Works haha;P Now i just need to get a GameBoy, and that shouldn't be too hard, they are kinda cheaply available where i live. The GameBoy doesn't have any region differences in the hardw...

Might as well ask this here as the topic is fitting. Been looking for a Flash Cartridge and Flasher (or both in one thing) as i talked about in the other thread. As i need those in order to run tests on the original hardware. Finding these stuff was harder than expected (except super expensive ones)...

Ah, would have thought something that could write would automatically be able to read as well, that explains it. Seems quite hard to find these flashcarts, except some super expensive ones, not even Reader/Writers, perhaps i am searching wrong:S Ah okay, thought it was some kind of serial connection...

Ah well obviously i would need more than one for any kind of link tests, pretty hard otherwise xd Confused when you say you can put a ROM on the flashcart, and later you say if you don't have a flashcart reader you need to print visual statuses. How would i even get the ROM to the flashcart without ...

Yeah learning more and more about that, first when i started my GB Emulation just for fun (never doen ANY emulation before) and got much help and explanation how things worked. But as i went deeper i noticed that it was lacking and something were kinda controversial. So i think it would help to do t...

My bad missed that part about LY being reset directly on Disabled.

Will check the tests about the timing, thanks:)

Yeah it sucks that random stuff are inaccurate, and as i don't know how to test the stuff myself i have to rely on documentation from others. Would probably get a gameboy for the purpose of testing the behaviours, but i would probably need other hardware as well to do proper tets rather than just lo...

In that case it LY also reset, cause otherwise it would go out of sync with that clock right?

And also, when it's disabled, is the clock stopped, or does it run and it just resets when re-enabled?

Ah, but what if you write to LY so it resets?

And also when is the comparison done otherwise, is it done at the end of HBlank?

Good to know, quite hard to understand what the intended effect is. The same goes with Amida during the intro, one frame the sprites that are going to turn left are glitched (right before switching from going down, to left). I thought my emulation was wrong, but it seems other has that as well, no c...

Is there any place to get those Hardware Traces?
As it seems to be quite rare to find what the CPU actual does every clock (even Machine Cycles).

Tried now on VBA-M.
It does look as one would expect a Demo to look like when this is one.
Can imagine if the LCD was slow that it would look like this cause of the ghosting.

Does someone have a real GB that they can test games on? There is one game "Serpent" which behaves very weirdly in it's drawing on mine and other emulators. I am doubting it's really how the game should act cause it's flickering like mad. So if anyone has that game and a GB to try it on i ...

As title says.

I would imagine they being checked each LY increment,
but what happens when the actual flag to check is set, does a check occur at that moment, or will it wait till the next LY increment?
