As I told Hyper, the Bingo rules still need some refinement.
In Sonic CD, what most games call Acts are instead called Zones, with the traditional Zones called Rounds. So "Complete Quartz Quadrant Zone (Sonic CD)" allows me to finish after Zone 1 instead of the full round as intended. Likewise, Chaotix calls Acts Levels and Zones are called either Stages or Attractions, depending on where in the manual you look; the game has one Zone called Newtrogic High in which everything else takes place. This would make any "zone" request in Chaotix infeasible as the entire game would need to be played, and there wouldn't be any way to do Act challenges. Sonic Heroes has Special Stage Act 1 all the way through Act 7. Heck, Sonic Adventure calls them "Action Stages", and this name sticks around for a few games. A standard definition of a single stage or area needs to be made and explained for every possible game.
For "Obtain x Chaos Emeralds", does story progression count? If I beat Casinopolis in Sonic Adventure as Sonic or Tails, I have two Chaos Emeralds for about 30 seconds before Eggman steals one.
For "Score x points on any Act y", can Special Stages be used within the Act? Do I need to finish the act, or does it count as soon as I reach the point requirement? For "Score x points on 1 zone", do I need to finish the zone, or does it count if I finish the act in which I reach that amount, or does it count as soon as I reach the point requirement? If a game doesn't have zones, can I score a certain amount in one area of the game?
For "Get 10 S/A Ranks", if I get an A rank in a game that supports S ranks, does it still count?
If I need to collect a certain amount of rings, how do I deal with a ring counter that maxes out (Chaotix) or rolls over to 0 (many 8-bit games)?
For "Collect x rings between 2 acts of the same zone", must those two acts be consecutive, or may they be any two? In this case, must I finish the entire zone, or may I stop after my chosen second act? Likewise, does "Collect x rings between 2 zones" require two consecutive zones? If I finish this in one zone, must I play the second zone anyway?
For "Get x lives", does that mean I increase my life count from the default to x, or do I *earn* x lives and end at the default + x? Does it mean within one game, or across my three games (e.g., "Get 20 lives"; my three games start with life counts of 3, 4, and 4, and I end with 10, 15, and 6, for a total earning of 20 lives, or the same but with the initial 11 counting towards the 20)?
SRL rules say to start from the title screen for most Sonic games; do we have three title screens running at once to start, or do we boot one game at a time (i.e., two games start from powering on)?
For the "five separate bonus stages goal", S3&K has three, Chaotix has one, and Spinball has four. Thus, at least two of these games must be used (except the S3&K/Chaotix combination)... doesn't that lock in your game selection a little tightly, since you can only use three for the entire card?
SRL has game listings for several Sonic ROM hacks (my hack, MegaMix, and a broad "Sonic 1 ROM hacks" category without a matching one for Sonic 2 or 3&K); I assume that the Bingo allows official games only?
More problems to come as I see them, I'm sure...
