What I meant is that anyone who plays Lady Pac ONLY on a PAL machine (without comparing it to NTSC) would not say that the game is slow. I tested the game on PAL myself during development, and never thought "Oh no! It's too slow".
As I said, it's not just about adding a delay counter like in Jumpman Junior. I should recalibrate the speed of Lady Pac, the speed of each single ghost (considering it increases round after round), and the speed of the fruits (both in normal rounds and bonus rounds). In addition to this, I should also recalculate the time during which the ghosts chase Lady Pac or go around randomly (this also changes round after round), the time during which the ghosts become edible (this also changes round after round), the time before the fruit disappears, the delay counter for the timer in the bonus rounds, the times for animations, and many others. Also consider that speeds and times must be recalculated based on the chosen difficulty level (Easy, Normal, Hard, Expert). It's a lot of work, and I personally don't think it's worth it.
If you find it appropriate to modify the disassembled to have your own version of the game, go ahead.
Anyway, thanks for appreciating what I have done.
