Whenever I'm playing a game via emulation and I get stuck, I do end up wondering if it's a bug in the emulator. This particular issue, I would have assumed the game was designed this way it and is just difficult.

Not quite related, but i get a similar feeling if the game seems really tough: "is this due to emulation latency". I went down a rabbit hole on this one and built myself a mister FPGA!

Chronic Trigger had one like this. I recall there is a section where you catch a rat and have to input four simultaneous key inputs after catching the rat. But usb inputs only forwarded 3 at a time so to get passed this you’d mash all four and eventually you’d get them registered inside the very short timeframe. Took many tries and was very frustrating.

> Chronic Trigger

Sometimes it does feel that way...

Yeah I hit that bug a long time ago, my keyboard at the time only had "2 key rollover" - which I think was standard. Current gaming keyboards have NKRO - "n-key rollover" which would allow the four "buttons" to be pressed at the same time
