RetroAchievements is a service integrated with supported emulators that adds achievements to retro games. I am an achievement developer, Code Reviewer, and member of the Developer Compliance team.

Date with Falco
Set Released 27 Nov 2024
10 AchievementsIcon, Badges: Layton
A furry gay dating sim wouldn't normally be my kind of game (being neither gay nor a furry), but I had to check this out when I saw it while browsing itchio. Its more genuine and well put-together than I expected and I figured it would make for an interesting set on RA, so why not?
The snowball minigame was interesting to work with, its just a timed sequence and the game doesn't keep track of any sort of score. I detect when a snowball hits falco by looking through each object and identifying it as a fox snowball and using its X position when it disappears to know it made contact and increment my own score counter, and the same with falco's snowballs to decrement it to incentivize avoiding snowballs. Throwing snowballs consecutively is a bit unreliable so I made the achievement score threshold low. -
Super Mario Bros. Mini
Set Released 21 Nov 2024
75 AchievementsIcon, Badges: Layton
Special Thanks: Mico27
An article appeared on my phone about this homebrew, I thought it was neat but what really interested me was the new content. Worlds 9 ~ 16 feature new levels with some familiar-but-unique-to-SMB1 bosses.
The memory was tricky to work with at first and required more complicated achievement logic than I would've liked - so naturally I made a pull request on the game's Github and added game variables myself. One of these times I'm going to add actual content to a game (or more likely make my own), and after that I don't know how to take this any further. 😆
I wanted to do more level specific challenges since the game has a readily available level select, but I couldn't come up with anything else good. -

Wishing Sarah
Set Released 28 May 2024
21 AchievementsIcon, Badges: Layton
Special Thanks: Yin
I played Dreaming Sarah in 2015, and I think the creator dropped by one of the Dream Diary Jam discord servers when I was active there one time. When I saw the series had an entry made in gbstudio I knew what I had to do. The game is short but has some hidden secrets, so I had to reach out and get some developer advice on this one (thanks Yin!)

Borbo's Quest
Set Released 14 May 2024
9 AchievementsIcon, Badges: Layton
I came across Borbo's Quest while I was a junior developer and prepared a set plan, but shelved it for later as the small set wouldn't have helped me through the program. I forgot about it for over a year until I found the plan in my files. While appearing as a Game Boy game, the CGB flag in the rom's header at 0x143 indicates its a Game Boy Color rom that is backwards compatible with Game Boy.

Puppet Zoo Pilomy
Set Released 29 Apr 2024
12 AchievementsIcon, Badges: Layton
This game presents itself as educational, but it gives off an unsettling vibe that at any moment it could dive straight into horror. You create puppets from animal parts and give it a heart, bringing it to life. Placing your puppet in different worlds allows you to travel there and view your puppet in motion (or not). You can mix and match parts of different animals and place parts where they don't belong in order to make chimeras. The game doesn't force you to and gives out parts in complete collections per animal, but at the end it starts giving out randomized parts to aid you in doing this.
Overall the game is short and light on unlockables. Once you make 32 puppets a cutscene plays and you can view the credits at the Cinema, but nothing else happens.
Despite being Japan-only it includes full English.

B3313
Super Mario 64: Internal Plexus
Set Revised 23 Apr 2024
273 AchievementsIcon: FBernkastelKues
Badges: Layton, FBernkastelKues
Documentation: BikdipOnABus
Assistance: Rolly Polly
I revised B3313 to update it to the newest release. I initially wanted to make a separate set as the game had changed dramatically, but I think replacing the old set was the right call in the end. Through the revision process it was decided to have achievements for each world and lobby, adding at least 240 before considering other new content. It was a big effort but I made heavy use of BikdipOnABus' documentation and had some help from b33 community member Rolly Polly with organizing the lobby achievements. I used my processed info to make a Parallel Star Display Layout, so if you're using Parallel Launcher you can view a window showing which stars you've collected. The achievements are designed to serve this purpose but its a nice option for those wanting to 100% the game without using RA, and I'm listed as a contributor so that's neat 😅
The surreal dream-like atmosphere of the hack drew me in, reminiscent of Yume Nikki and LSD Dream Emulator. The creator never played either of those games and wasn't directly inspired by them, weirdly enough. I like exploring pre-existing areas of games with changes, like Fyrestone in Borderlands 2 or the tweaked maps in Combat Arms' Quarantine mode.
By the time I was done updating the set I was real tired of looking at the game, but I'd like to return to it at some point and play through all of it again. -
LSD: Dream Emulator
Set Released 31 Mar 2024
156 AchievementsIcon, Badges: Layton
Documentation: higashi
Special Thanks: thegotoguyy
One of the most highly requested games (for a while *the* most highly requested), LSD was known as a cursed game on RA. Multiple devs had tried to make an achievement set for this but were unable to for one reason or another. The game was widely believed to have memory too complex, or to have behavior too random to make a decent set.
I initially checked LSD out earlier in my dev career - I had played it before but I believed even if I understood the game's memory (I didn't) that it was too boring achievement-wise. I wasn't aware of the amount of content LSD truly had. When I heard of the discovery of the interact button I realized an achievement set could be possible, but I still wondered if people really wanted a set for such a game. In March '24 the set was dropped again. I wasn't particularly interested in continuing the work myself, but I was curious what was left - my impression from the outside was that all the pieces were there and there wasn't too much content to cover. This wasn't entirely true, there was still a large remaining piece - detecting an object's state.
In LSD encountering an event impacts the game's internal graph value, influencing future events. When a dream ends the game displays the graph, and the resulting tile indicating the mood of the dream. This graph is actually active at all times, and the current tile is changing constantly. Aside from being reset when encountering special dreams, there are two things that influence the graph: walking into different 'chunks', and seeing events. These don't set the graph to a specific value, instead nudging it into a specific direction. For both of these the game stores the most recent (x,y) pair which can be used to detect when an event has occurred. There are a couple of events that share the same values, and while I was able to bypass this if the events were on different maps that still left a couple instances where I couldn't use this value to differentiate between certain events.
The gunman in the Violence District can be knocked down using the interact button, but this didn't trigger a unique event value. The only way to detect that this occurred would be to check the gunman's state directly, but it wasn't known how to access this. Multiple gunman can exist on the map, and their state values were in different addresses each time the area was entered, indicating pointers. I was told it was likely a linked list, not having encountered one before I loaded the game up and looked for it. That night I found the linked list, and with the last piece of the puzzle I figured I should go for it and complete the set.
There were still some challenges such as actually using the linked list in achievement logic, but I was able to sort it all out in the end and the set has been received fairly well. I'm happy with how complete it is content-wise, though some of the events are very rare if you don't follow steps to manipulate the graph values. This wiki was very helpful, I wish I had found it earlier. Specfically these two pages. I used my knowledge of the linked list to add an entity list to this debug overlay menu LSDebug, which I also wish I had done earlier.
I never found a way of detecting the current texture - depending on the day the game can choose up to 4 sets of textures in each area. The texture is chosen on map transition and we don't have access to vram for achievements. From a set design perspective I don't think this really matters, but I spent a good chunk of time trying to figure out a method. -

Tail of the Sun
Set Released 25 Dec 2023
61 AchievementsIcon: Sines
Badges: Layton
I knew the set for Tail of the Sun would mostly consist of finding all the interesting landmarks scattered across the world, but I had no idea how many there were or where exactly each was. Before working on the set I purchased the official guide hoping it would include a map, and luckily it did. This map isn't very accurate but it gives a rough idea where each landmark is located.
What the guide didn't give any information on, however, was how to trigger each of the 9 endings. Some of them are tied to having a high value in each of the character's stats, but some of the endings were completely unknown. I ended up using a debugger to read the assembly code directly, and was able to piece together the requirements. I doubt anyone had ever encountered some of the endings before, so its cool that the set now facilitates that. -

Battle Unit Zeoth
Set Revised 27 Aug 2023
5 AchievementsIcon: (Unknown)
Badges: Layton
I revised this for the Beaten Into Completion event, adding progression achievements so the set could properly track beaten status upon beating the game. Battle Unit Zeoth was the eligible game that most interested me, but its not a game I had a history with or would've been interested enough in otherwise. I believe its important to only make content for games I care about and have a particular interest in, but I think this game is alright and I don't mind maintaining it.

Gekibo: Gekisha Boy
Set Released 15 Jun 2023
28 Achievements
Icon, Badges: Layton
I wasn't satisfied with the existing English translation so I retranslated the entire thing. My lack of experience with romhacking meant I was limited with the length of each text string, but I think it turned out well. It is much more faithful to the original, and the hints are more accurate and make completing the game a bit easier.

Frogger's Adventures 2:
The Lost Wand
Set Released 28 Jul 2022
39 AchievementsIcon, Badges: Layton
My first achievement set, it ended up being a good first pick as I was able to utilize a lot of the toolkit here. Its been chosen twice for Achievement of the Week (In 2022 and 2024)
While working on this I discovered that you can replay the last boss fight and level by pressing Left/Right on the main menu after inputting the Magician's Realm title screen unlock code. Pressing L on the title screen lets you play through the bonus levels back-to-back in a random order until you fail as well.
The Japanese version also has some small level differences.
