NBA JAM TE on Mame4all - Wiz

Home / Forums / NBA JAM TE on Mame4all - Wiz

Hi guys,

I am trying to run Nba Jam smoothly on mame4all. As suggested, I set to cpu at 800 MHz (even at 830 MHz, the max in my case) and the video aspect at scale.

I load the rom no problem but I am having performance issues such as poor framerate (auto frameskip at 7), slow and choppy gameplay. Cpu clock and audio clock are both set at 80%. Same poor results were observed on mame4all 2.4, 2.5 and 2.6. I know that Midway's games are tough to emulate...

Does someone run nba jam smoothly ? If yes, what are your settings ?

Thanks !

Tried with the Mame4all offered version but still am having performance issues. The game is slow, auto frameskip at 7. However, I am running other roms (f.e. Mortal Kombat and Outrun) flawlessly at 830 MHz, solid 58-60 fps. My firmware version is 1.2.6. Maybe my wiz doesn't like basketball games at all ;) Thank you for your help !

Hi Naru,

Using the same rom set as you, with MAME4ALL at the recommended settings. I wonder if I've been using a different release than you? Try downloading the file which I offer game.zip and see if using the version & configuration of MAME within that file does it for you... Let me know!

Hi Nick,

Indeed, I am playing both roms with exact same results (nbajam.zip and nbajamt1.zip). At 800 MHz and with the screen mode to scale the gameplay is choppy and slow (autoframe skip to 7). Maybe my roms are bad...I am using roms from the MAME GP2X_Wiz 2.2 Full Romset. Where do you get yours ?

Are you playing the standard ROM nbajab, or is it Tournament Edition? Personally, I've been able to play nbajam at 800 mhz (screen mode to scale) without a hitch. I'm running a version of Mame4All from the game zip file available for download from this site.
