why does truxton have so much slowdown and not run at constant 60fps ?

the second one plays nice and smooth.

Ive done a tidy up of alot of code...... everything is now tested and R4 is nearing completion. This will add a bit more but tidy up some stuff including adding a few more Manufacture sorts.

Cool! This emu is amazing. But what about Crystal of Kings? Could it run on Xbox? Thanks for everything!

there is a really good shooter called vimana by toaplan which i have been playing on coinops lately.i know the sound on a lot of toaplan shooters isnt fully emulated yet but i do remember reading somewhere about a process called decapping.

do you know if they have got any futher in actually getting the sound emulated yet iq???

Nope, no progress afaik. If you check Guru's decapping list, a lot of the mcu (also the sound cpu) chips are needed.

Highly unlikely.

 

 

 

 

 

 

 

 

Here's a good way to tell if a game will be playable on xbox. :D

 

Run your mame game in windowed mode on pc

mame -window kof2003

 

Open up the task manager

 

Record the average %cpu mame uses for this game (not intros, IN-GAME).

Next, add 5 to this as newer cpus are more efficient than the one the xbox has and MAME has gotten slower.

We will call this percent-> GAME_PERCENT

 

Next, find out how fast your CPU is in mhz

So if it is a 1.8ghz dual core cpu your ghz is 1.8 * 2 -> 3.6

next, multiply this by 1000

so your mhz is 3600

we'll call this number CPU_SPEED

 

Next, find out how much ram this game takes. If it is over 60mb, you're likely going to

need to use the VMM. This takes, I'll guess, about 5% more cpu.

If this is the case, add 5 more to GAME_PERCENT.

 

 

Now, here's a quick formula

(CPU_SPEED * GAME_PERCENT) / 100

 

just plug in the values as necessary. :)

 

if this value is above 733, it will very likely run like crap on the xbox.

 

 

 

 

 

Here's an example

Night Slashers takes ~23% cpu on my system.

I'll add 5% to this, making it 28%

I have a 1.8 GHZ c2d. So I would do (1.8 * 2) * 1000 -> 3600 mhz

Night Slashers also needs the VMM.

I'll add 5 more % to the GAME_PERCENT, making it 33%.

 

plugging the values into the equation:

 

(3600 * 33) / 100 = 1188mhz is required

 

Taking this even further, you can calculate about how many fps you should get.

 

733 / (1188 / 60) = 37 fps.

 

[note that ~60 is the normal fps for most arcade games]

 

 

 

This isn't 100% accurate, but it's close enough in most instances. :)

martimimelle shows up on the romlist for me,you have go by its proper name power instinct martimelle.

as for b rap boys there are some graphic glitches that is already known about but it plays for me after the second stage.

 

@iq132 i noticed that power instinct legends the third in the series of these great beat emups is not in coinops would it be possible to add it to your list.

thanks as always.

sega model 2 arcade hardware on xbox,the xbox just dosent have the power under the hood to emulate that game alvarez.

its one of the greatest if not the greatest arcade racing games ever,so if you have a dremacast then i would suggest you hunt down daytona usa 2001 which is an arcade perfect port with extra cars and tracks.
