I've spent the last few weeks building a mod runtime for the iOS version of The Binding of Isaac: Repentance.

Before I decide how to release it, I'd like to know if there's real interest.

What works today (on my iPhone 15on iOS 27.2)
A Lua mod loader that runs original Workshop mods unmodified

A native Mods entry on the pause menu, styled like the game's own papers

Mod Config Menu working through touch

Per-mod ON/OFF toggles

Mods I've seen running include Enhanced Boss Bars, the POG/Specialist/Ugh item mods, Missing Costumes and Hanging Dream Catcher (partly)

What doesn't work: a lot of API calls mods expect aren't available on iOS. Many mods load but only partly work, and some can't run at all. It is not REPENTOGON, and none of REPENTOGON's callbacks fire yet. Expect bugs, and expect it not to be a one-tap install.

My questions
Would you use a limited-but-working modded Isaac on iOS now?

Or would you rather I wait for a proper REPENTOGON port and publish nothing until then, if that's even realistic?

If I release, what matters most: specific mods, MCM, item descriptions, or stability?

How I'd release it: the mod runtime and patch tools only. You'd need your own legitimately purchased copy of the game, and I wouldn't distribute the game or its files. So sideloading, and eventually .dylibs to attach straight with livecontainer or sideloadly.

Credits
This builds on a lot of other people's work.

iOS tools

emp0ry made Isaac External Item Descriptions for iOS (native in-game item descriptions) and IsaacSteamSynciOS (native Steam Cloud and achievement sync). Both are MIT-licensed, and their notices are included.

wofsauge and contributors made the original External Item Descriptions mod, on which the iOS version's data is based, and the translators deserve thanks too.

Cannot remember who made the Debug Console mod and can’t be bothered to search rn.

Same for IsaacFixes, which gives Drop, hold-to-restart and similar fixes.

Thank you all. If you're one of these authors and want something changed or removed, message me and I'll do it right away.

Happy to answer questions or share screenshots.

If I go for Devil deal I can secure at least 1 item per floor, 2 if I get deal. Meanwhile I can secure 2 angel items per deal, even more i get lucky and get an angel statue on super secret room. Im going for beast, whats the safest bet (someone help, tlost is torturing me)

can midas' touch actually appear in greed treasure rooms? ai says it does, wiki doesn't explicitly say either.

So from what you can see, this is heaven...

What is bad? I've cleared 6 rooms and I have so many chests already and I have a ton more room to go and clear...

(I have sharp plug, pyromaniac, habit , swallowed penny and Counterfeit Penny somewhere in my items so holy chest dupe)

It will be a long run especially after using the r key and doing this YET again.

(Btw,for those who doesn't check what they unlock or exist,found out in 200h that there's an item that could give you more health to your t keeper or just keeper, it's Greed's Gullet)

I'm 122 hours in, I've got 237 out of 641 achievements, and this one by far required the most effort from me and made me lock in like nothing else.

My playthroughs were as Eden, Cain, Samson, Magdalene and Azazel - in this order.

With Eden I was just playing around, but suddenly got a good run and decided to start my journey to this achievement.

Guides never suggest Magdalene for this for some reason, but for me she always seemed as a safe option cause of her tankiness. When the original Binding of Isaac came out I got Platinum God in it - I picked up Rebirth with all dlcs only relatively recently - my memories of playing her in the original game also somehow comforted me, so I picked her as one of the last.

With Azazel I got pretty familiar and confident in the Rebirth - he was my workhorse for unlocking all of the Repentance content. I picked him up as the last - and I was extremely nervous playing cause of his health pool. His run started terribly - with Range Down pill and no good pickups in Treasure rooms for several floors.

But everything turned out to be ok: I bought 4.5 volt battery in the first shop in the Basement (earning money by destroying the Donation machine) and in the Womb I got Satanic Bible right when I needed one. So I entered Sheol with the Emperor card and a full health pool - except for missing red hearts, cause I drained them with blood donation machine to make the Polaroid work.

All my runs were to Sheol with the Polaroid, for some reason the Isaac boss has a habit of screwing me up pretty badly. I'm bad at avoiding his tear bursts. For me Satan seems like a much more predictable boss. Except for Cain - his run was at the beginning, got pretty broken, and I decided to ascend and slay the Beast, and was successful at it.

So yeah, now it seems like I can play relaxed at last, not caring about the bad rng or the losses.

The reward itself I'm not sure how helpful, I'm pretty bad at spotting marked rocks everywhere except the basement

I finally beat ultra hard, took a lot longer then I’d care to admit, but it was such a fun run, even for ultra hard I had to share. AND I saw this at a holiday festival after!

The gift that keeps on giving 🙂‍↕️ 🎁

Whenever I pick up a pickup or an item it changes the room and gives me a random delirious to fight for me

Beat mom's heart real quick, a few more times and ill unlock more bosses

On xbox you can get afterbirth/+ and repentance as dlcs for rebirth or just buy TBOI Repentance and get all the dlcs does anyone know if there's a difference between them or which is better to get?

No but actually, where tf is he?? I beat it lives before 30 min, why is there no entrance to the blue womb?

Imagine there was a boss called "Dad?" and he threw down milk cartons that explode and turn into milk puddles, soy milk would just be a circle of many, many rotating bullets, almond milk idk would make psychic worms, chocolate milk would make a giant splitting bullet that has the flat stone effect applied to it, and when you defeat him you unlock... Strawberry milk. It would maybe severely decrease fire rate, increase damage by like 1.5x and increase shot speed by 2x, basically a gun.

"Blood Drainers"
Quality 3
Only found in the devil, demon beggar & curse room pools.
Dmg Multiplier X0.8
Every 5th tear becomes a Leech tear that inflicts the Leech status on an enemy.
This status causes an enemy to take 2 DMG + 1 DMG per floor every second.
This effect can be stacked and lasts until the enemy dies.
Killing an Leeched enemy has a 10% + (5%*Luck) chance of healing 1/2 a heart.

The second picture is from original post and the first one is that i made

tl;dr skill issue & I needed to r a n t

I would have never guessed that my highest lost streak in TBOI is gonna be with that mf. I know I'm not the best player, but I have to be even more precise than I had to be with t lost, j&e or t jacob...

I actually enjoyed those challenge characters cause they make you excell in the game and have a lot of upsides and exploits

But this sh*tter??? NO! The poops do not help you at all, only during the first couple of floors when they let you deal with the enemies because his base stats suck 😭

Inb4 yes, I do know all the poop gimmicks, it's just so much harder to get a decent built with t bb than with other characters for me

It was my birthday yesterday and she got me this, she thought it was from tboi but I told her it was so she wouldn't feel ashamed, I even named him el toot toot

every time i run either epipheny,unique items api or arachnia mods this error appers
