Maybe. Final Fantasy VII was the turning point for the PlayStation, and would've likely been a Nintendo 64 timed exclusive (or console exclusive) had the N64 had a disc drive.
Is there a chance third-party companies were getting so fed up with Nintendo that they would still support PlayStation much more enthusiastically even if the Nintendo 64 had a disc drive? Possibly.
I think we would've seen a strategic tie between the N64 and PS1 in terms of hardware units (About 64 million each, give or take a few million). Basically the Xbox 360 and PS3 difference of a few million (within margin of error). Nintendo would be going into the sixth generation with a far stronger foundation in terms of sales and would use DVDs (or something similar) for the GameCube instead of miniDVDs.
