problems with Virtua Striker 2 and Sports Jam

[MaYooD]

Hi Guys
Im new here to the forums.

I have been running these two games virtua striker 2 and sports jam on Nulldc 104_r136 (I assume its the latest version). I have those games on my dreamcast console but I always wanted to play them at Higher quality than what the dreamcast offers as much as as I can , and I assumed that can only be done on nulldc. The problem is that both games get a bit laggy (tried both cdi and gdi). my settings on nulldc:

Resolution: maximum supported (highest quality)
Aspect Ratio: strech
Paletted Textures: Dynamic,Full
Sort: triangle
Modifier Volumes: Normal and Clip(slowest,highest accuracy)
Zbuffer mode D24fs8 (fast when available , best precision)
texture cache mode: delete old

and I play the games on full screen with my laptop hooked to my 42 inch hd tv.

for my laptop , its a macbook pro with windows 7 ultimate 64 bit installed on the boot camp. with a processor 2.66 GHz , 8 GB ram.

I dont know if the problem is from the laptop, nulldc, or the games themselves.
please if someone can point out in case if there is a better null dc version to play those games, or are there better copies for the games.

thanks alot

It's your system specs that is the problem and no that is not the latest version of NullDC but upgrading the version will not help you

If you run in VGA mode it will look very nice on a large screen anyway I run my Dreamcast on a 43 inch TV via VGA, you do not need to make it run any higher than 640x480

Buy a VGA cable or box for the Dreamcast or mod your dreamcast to have a VGA port and enjoy

Some games will need patching for VGA mode to work and there are 16 english games that don't have VGA supported

nullDC v1.04 r150.zip is the latest version, I obviously did not compile that one though, I did not re pack it either with respect to the guy that actually compiled it from the official NullDC source files

The games have nothing to do with it specially as you tested a GD-Rom dump as well, there are some games made into Mil-CD aka selfboot in the past that had issues due to the build of disc but that is in the past if you grab newer builds

Revision notes:-..There are some speed boosts so you may get lucky in the newer revisions.
