VIDEO: Why is Nintendo 64 emulation still a broken mess in 2025? (www.youtube.com)

The Nintendo 64 has always been a difficult machine to emulate correctly. But in 2025 - we should be well and truly past all of it right? Not exactly. Issues with Plugins, performance, graphical glitches, stutters. Unless you have a very powerful machine, these are common things many of us will run into when emulating the Nintendo 64. But why? And Is there any hope for fast, accurate N64 emulation in 2025 and beyond?

People tend to overstate FPGAs. They are designed as software in a funny programming language and then "burned in" to hardware. They can and do have inaccuracies and bugs.

In the long run, real hardware is going to disappear through the attrition of time, so we do need this stuff for the sake of preservation. But people tend to put it on a pedestal without really understanding it.

I did some FPGA programming in school, so I totally get it. The hardware is really amazing, but the janky proprietary development toolchains not so much. Plus, Verilog is kind of a pain in the ass.

Even hypervisors can have software bugs - running GBA games on the ARM9 core in the DSi is possible and even closer to "actual hardware" than a FPGA, but there are still weird side cases and glitches that only happen on this setup rather than actual GBA hardware.

FPGAs aren't some magical hardware clone that bypasses software issues.

That depends on the accuracy of the core on the FPGA.

Your comparison of GBA on dsi is kinda like saying "my dos games didn't work well on my windows 2000 computer" same cpu sure, but OS and hardware 'locations' aren't necessarily the same.

on the accuracy of the core on the FPGA.

Or in other words, FPGAs aren't miracle hardware clones and depend on the quality of their programming. Exactly as I said, got it.

Your comparison of GBA on dsi is kinda like saying “my dos games didn’t work well on my windows 2000 computer” same cpu sure, but OS and hardware ‘locations’ aren’t necessarily the same.

Which is why I mentioned it's an hypervisor, not running as if it were natively supported. It's more analogous to original hardware than a FPGA, though. Your analogy to DOS and Windows 2000 however shows you really do not understand how GBA2Runner or FPGAs work in general.

Your comment is got any point or it's just these two incoherent sentences?
