I remember back in 2006 when I first played rr7 when starting a race with Rverse Nos Charge and the nitours 1x plugin it gave you 2x nitrous instead of only 1x nitrous..
I remember setting a GTA with this setting back in 2006 only weeks after rr7 came out but as I sold my ps3 soon after and moved to england, when I bought a new ps3 and rr7 that GTA was gone and that plugin no longer worked for Reverse Nos.. I thought it was due to me being in england at first but when I seen my GTA was missing I just thought Namco updated the game somehow but I don't remember any updates so how did they prevent that from happening.. Does anyone else remember this??
I don't remember exactly how it was but I have never seen 2 nos w/ plug-ins, but I might be wrong. Haven't touched RR7 for a while.
About your GTA, it's been 4 yrs since it came out and a lot of people have tried GTAs, so yours might have been pushed down.
Nothing in RR7 update actually fixed anything game-play wise.
When I started playing in late 2008, there already was only a single starting tank with RNOS, even with the NOS+100 plugin equipped.
The only update they ever released afaik was last year with that strange 3D upgrade...which didn't seem to actually do anything to the graphics at all
The only car right now in the game that has 2 tanks ready at start is the Monstrous...
