MrSanRamon's table is priceless. I can't tell how many times questions have come up about which ROM is best for HS2 and the best I can say is "I've read a bunch of opinions, and the consensus is that L-2 is the least buggy."

The RLM bug that is understood only by pinball_keefer is the kicker for me, and is the main reason I run L-2. It can seriously affect a good game. The Secret Mania bug I avoid by not starting Secret Mania, and the endless multiball, I've only seen once.

Being an embedded software guy myself, I would guess that the endless multiball is due to an overflowing timer, but that's just a wild guess. Something like the below psuedocode is a common problem:

[CODE]
//timer is freerunning 16 bit counter
if(multiball_starting)
{
multiball_start_time = timer;
free_ride = TRUE;
}

if(timer > (multiball_start_time + free_ride_time))
{
free_ride = FALSE;
}
[/CODE]

The bug occurs when (multiball_start_time + free_ride_time) is greater than the max value of timer (65535 if it's an unsigned 16 bit value).

Again, this is all just theoretical.

It's not about the reward for me. If I had access to source code, I'd be on it in a heartbeat. Starting with a ROM image, disassembling, and trying to decipher, is a whole different ballpark, though.

If this is accurate, it makes it sound even more like a timer rollover problem. An 8-bit counter would roll over at 256 seconds.
