This is based on s1disasm_git, changes in this branch are my work but only that. For the purpose of the Archipelago experience, the following changes have been made:
- Sonic doesn't lose lives when dying.
- SRAM has been enabled to persist AP data between runs.
- Press C on a pause screen to immediately exit whatever level you're in.
- The inital start screen is removed in favour of direct to Level Select
- Since the start screen is gone, the Demo loop is also gone.
- Level Select has been overhauled to display the AP data so you can tell where to hunt.
- Level Select level order corrected, obviously.
- Due to how AP gives you rings, and space constraints, Sonic always drops 6 rings when hurt.
- For sanity, you don't get extra lives when you exceed 100 rings. Your ears should be grateful.
- The top 50 ring secret route in SBZ2 is disabled. There's no checks up there.
- Spike damage is now slightly less terrible.
- Monitors in MZ3 without state save and monitors in SBZ2 that should have been invis blocks have been corrected.
- Because AP, a mechanism for monitor state persistance is added.
- Because AP, content of monitors are all now 10 rings. Sorry.
- Because AP, Special Stages are played strictly in order until completed.
- Because AP, Special Stages completion and emeralds are divorced. AP got the emeralds.
- Because AP, boss completes are recorded now.
- Because AP, each set of zones are gated to AP key items.
- Special Stage: Don't offer special stage at the end of a level.
- Special Stage: Return to menu after exit.
- Special Stage: AP-toggled deactivation of Goal blocks, they turn into normal on touch.
- Special Stage: For byte alignment reasons, the UP block is now disabled.
- Special Stage: Continues jingle removed, result screen delay reduced from 6s to 1s
- Special Stage: Special stages are also gated to AP key items.
- Technical change (you won't see): Monitor objects have had the item field replaced with an id
- QoL ReadySonic change change: Scuffed SpinDash based on ReadySonic. And due to dependency...
- QoL ReadySonic change: Sonic incorrectly use his walking animation when near solids.
- QoL ReadySonic change: Sonic use his pushing animation while walking away from walls
- QoL ReadySonic change: Fixes problems with camera not catching up at high speeds, as well preventing Sonic from dying in these situations (notably in the S-tunnels in GHZ1 and GHZ3).
- QoL ReadySonic change: Roll into Caterkiller
The details and theories of Archipelago mode:
- Each monitor in the game is an AP check. Completing the level doesn't release the level.
- Monitors stay broken, to help you track which you need to break.
- Emeralds are AP items, other people need to find them for you.
- Special stages contain a check instead of an emerald.
- Bosses trigger a check the first time you kill them.
- Infinite lives but not invulnerable.
- Once people find some of your rings you're safe from all but instant kills.
- Given S1 specials are kinda miserable to play, they're nerfed quite a bit.
At the moment I don't have any checks attached to the lamp posts. I might add such thing in if things seem too easy.
To clear the game from AP's perspective you need to beat the bosses and beat the 6 specials.
