Make sure to read all tweets, important informations

Amazing, thanks!!!

Piece of advice to anyone updating, make a save state of games you want to continue before changing. The traditional save I had on Mario 64 was gone when using the new core (it was as if i had started a brand new game), save states do still load so you can re-save following opening up the save state

Savefiles will not work, it will just ignore them
It should not be deleted tho.

Also

Please note: Savefiles don't work, Cheats don't work either. Savestates work, but be aware that Mupen Next Savestates will NOT load on the nightly core!

Just a couple tests, Megaman64, Gex3, Goldeneye all boot, the first 2 play fantastically.

Yea golden eye is known to have huuuuuuuuge slowdowns

[23:10] Autechre: because that is normal
[23:10] Autechre: the framerate hovered from anywhere from 20fps to sometimes the low 8 to 9fps on a real N64
[23:11] Autechre: you can get it to run at somewhat acceptable framerates with overclocking on an emulator
[23:11] Autechre: however*
[23:11] Autechre: the problem is that the game's developers 'speed up' the game's speed when the framerate hits a really low number
[23:11] Autechre: so when you overclock the N64 emu you will suddenly notice your character moving faster all of a sudden
[23:12] Autechre: that would be because the game is hardcoded to modify its speed at certain spots where the devs predicted the framerate would tank

Yeh I wasn't expecting miracles with 007. testing another bunch of known issue games now.

--------------------- MERGED ---------------------------

Pokemon Snap sadly still has issues detecting pokemon at all (with frame buffer on) and the analogue stick is busted for it.

Yea that will likely need a update of GlideN64

The AKI engine wrestling games (No Mercy, Revenge, VPW2, etc) now boot and work perfectly via dynarec.

Many thanks!

Technically its not even alpha

Conex · Jan 17, 2019

All tested with max overclock and frame buffer "True"

Quest 64 - Perfect
Mega-Man 64 - Perfect
Donkey Kong 64 - Runs with "some" slowdown (Mainly the waterfall at the start)
Resident Evil 2 - Cutscenes work but no actual gameplay gfx display.
Pokemon Stadium 2 - Works fine lot's of jittering due to asset loading first time (once all moves ina battle have been used it's perfect).

(These all had Major issues or didn't boot at all before)

It runs for me fullspeed, try disabling fbemu and use my dk64 workaround.

Without FBemu it gives me the camera issue where it snaps back constantly. I have yet to try your workaround settings, can you link them?

Actually I found it, nice works great

"For those wondering about DK64"

1. Start game
2. Enter menu and enable Framebuffer Emulation to "true"
3. Close game (if it was already on frambuffer true, just skip this)
4. Open game again and when the game starts make a save state.
5. Change back the framebuffer to "false".
6. Close game and open it again.
7. Load savestate (Camera issues will be gone and the game will run fullspeed)

Wowowowowowowow! I've been running Revenge with max OC on the cached interpreter and still not getting full speed. Love you m4xw.

reyyesrey · Jan 17, 2019

I've definitely only tried VPW2 and No Mercy, for full disclosure. Hopefully Revenge is fine too.

Same issue. More stuttering at stock clock.

How to get rid of this?

Update your /switch loader to the nightly version.

I also added a flag that recompiles more code, but less often.
So stutter is worse but happens less - at least thats what it supposed to be.
