Mario Kart 4 player

[Tirog]

hey, on pj64 mario kart runs great... too great.

See, some levels (the higher detail ones) run in super-speed. I believe the game cartridge is programmed to actually cap the fps at a lower rate (lower than 60, maybe 30?) on these levels during 4 player mode. It seems like the speed of the game is determined by the fps, which means that running these levels on my system (XP2600, 512 ddr, radeo9600), the game runs in ultra-turbo speed.

will 1964 v.99 have a fix for this? Optimally someone could hack the code in the cart (although I'm not sure how realistic that is... kindof like implementing good mouse/keyboard support for 007 and PerfectDark). However, another easy fix would be to be able to set the frame rate cap to 30 (actually to cap it to whatever the user wants). The game will seem a little choppy then, but at least it'll run the right way.

Anyway, will 1964 have a fix for this?

there are some things that might help. I haven't seen this myself, with the synch speed setting turned on, so it might be fixed already.

I know the levels you mean, particularly:

Bowser's Castle and
Donkey Kong Jungle

In one-player mode this is fine, but when it jumps to 2 players or more it's like the game is constantly mushrooming. Not literally, but super-fast.

Hmm... y'know what's strange? My real Mario Kart cart (pal), does that too... Is it supposed to do that?

 

[Burnpro]

yeah my own mariokart cartridge does that too.. it only happend in 4 player mode.. very funny indeed..

 

[Glurak]

It happens on my cart too but only sometimes...

 

[Tirog]

that's what I'm saying. The cartridge is programmed to do that. They knew that the system could only render that level at 30 fps, so they set it to do that. However, my system is a bit faster than a n64, so the game runs too fast.

Somehow the emulator has to be able to render the game without regard to the fps specified by the game cart.

 

[Tirog]

oh, I believe that perfect dark has similar issues... where the game cart predicts where slowdown will happen. I'm convinved that Perfect Dark will never run smooth until this issue is addressed.

 

[karth95]

I understand, and (please realize I'm not the author, and this is speculation) I think that if the timing in the n64 were perfectly emulated, it would work correctly. As it is, counter factors are used and the timing is not perfect, resulting in these speedups and slowdowns. I would assume (perhaps incorrectly) that if any n64 emulator ever perfects the multi-tasking timing of the n64, all these games would work correctly.

This "speed" issue is the same on the real n64 game. It's activated in certain stages, by dk's jungle one I know for sure and by playing 3 or more (2 maybe too?) players.
It's fun to play with too super-speed, yahooo!

 

[Clements]

DK Parkway is indeed super-speed on my real PAL cart. Reaches insane levels @ 150CC/Extra modes so that you can hardly turn without skidding and stuff.

lol its real funny when it happend to me the first time. I ran strait in to a wall and flipped over.

i wonder if mario kart dd has problems like this ?
lets hope not when its released
