Yes we were able to get a discount on the carts due to them being just the PCBs, and buying them in bulk. Also our carts don't have SRAM, since I use batteryless saving, so that might have saved money too, I'm not sure.
Sure thing!
Our carts consist of:
- PCBs with 8MB of space -- purchased in bulk from insideGadgets
- Cart shells -- purchased from AliExpress here
- Plastic cases -- purchased from AliExpress here
This gives us an inventory of physical carts. These carts work for all our games.
We get our cart stickers printed from Sticker Giant (Kiss Cut). These come on rolls from them.
For Inky and the Alien Aquarium, we did a full physical complete-in-box release. We get our boxes printed from UPrinting, our manuals printed and cut locally by FedEx, and our cardboard inserts from AliExpress here.
For Crypt Sweeper, we aren't making boxes or manuals, so the physical release is just the cart and plastic case.
Thankfully, our PCBs from insideGadgets came pre-flashed with Inky, which saves us a lot of time. But for Crypt Sweeper, we have to flash over Inky with the new ROM. We use a GB Operator for that.
All that is left is to assemble everything and ship it out 😅. We use rollo for printing shipping labels, and Pirate Ship for tracking. Etsy and Itch for online orders, and Square for in-person purchases. Also ULine for shipping envelopes and cardboard boxes.
It sounds like a lot -- because it is! But we didn't figure this all out at once, it's been a slow process over many years.

Hi all,
We've finished our next game, Crypt Sweeper, after ~2 months of development.
Links:
I thought this community might be interested in some of the development and history as well.
We have been working on a platformer for a while, but started to feel stuck. I'm always on the look out for interesting games, and stumbled on this article from ArsTechnica, where they clued me into DragonSweeper.
It took me a while to figure out the game, but once I did, it was really addicting! I kept discovering new mechanics and ideas, and fell in love with it. I thought it would be a great idea to port the game to the GBA, and reached out to the developer (@danielben). He didn't want me to use his assets, but suggested I clone the game instead.
This seemed like a project I could tackle in a reasonable amount of time so I got to work. I made a basic clone of how I understood the game, and then dove into the original DragonSweeper code to look at the level generation.
DragonSweeper's level generation is really interesting -- the basic idea is to place monsters on the board, then score how "happy" the monsters are, and wiggle them around until their "happiness" is maxed out.
I attempted to port this same basic logic to C, but when I ran it on the GBA, it took 40+ seconds to generate a level! This was not acceptable.
I ripped out the level generator, and rewrote it from scratch, based on my new understanding of how the game worked. There are a lot of constraints that need to be maintained, but in principle, it's still very easy. For example, the walls are always placed in pairs (horizontal or vertical). Most monsters have placement logic as well. Instead of encoding the preferred placement as "happiness", I just placed them directly in the structure I wanted, and gave up and started from scratch if I failed after 100 attempts.
The level generation still took a while though, 15-20 seconds (iirc).
My solution was to do all level generation at compile-time. This actually turned out to be a really good decision.
A side effect of doing level generation at compile-time meant that I could do additional analysis on the levels. In particular, I wanted to have 5 levels of difficulty, with harder monsters spawning on more advanced levels, but also the boards themselves needed to be analyzed for their difficulty in reasoning.
So I created an AI that could play the game, based on different amounts of understanding of the game. For example, the base level understanding is just math. But I could also add knowledge of how the monsters behaved into the AI. That meant I could run the AI against a board with different levels of understanding of the game.
At compile-time, I generate 1024 levels per difficulty, and in order to validate that a board conforms to a difficulty level, I let the AI play the board with a certain level of understanding. If it can beat the board at that level of understanding -- and not at a lower level of understanding -- then I can be certain that the board has a certain level of difficulty.
This does increase compile-time quite a lot, but it's a fixed cost.
This is a similar technique I've done for Sudoku boards, for example. It's hard to generate an easy board from scratch, but you can generate lots of boards, validate they have one unique solution, and categorize them after the fact. This is roughly what I do for Crypt Sweeper as well.
One last step, since the player only has 1024 unique levels per difficulty, that felt a little small. In order to increase variability, I also shuffle the two lowest level monsters randomly on the board, at run-time. These monsters are always placed randomly, so shuffling them around after the fact shouldn't alter the difficulty that much, and hopefully provides a tiny bit of variety at run-time.
Lastly, now that I had everything working, I got a little creative with the monsters. I did copy a lot of the monster behavior from DragonSweeper, but I added new monsters, variations of monsters, dropped some of the mechanics I didn't understand (gnome?), and reworked some mechanics specific to the GBA (Dracula's Ire).
After all that, I gave it to my wife, who did all the graphics and came up with the story. I wrote an 8-bit rendition of Moonlight Sonata for the soundtrack, and added final touches, like sound effects, and an in-game tutorial.
Anyways, we hope you enjoy the game! We decided to release it as Pay What You Want because we took so much from DragonSweeper, which is also a free game, so it didn't feel right to charge for the game. At the same time, if people want to give us money, that would be great, because it helps us make more games!
Thanks for reading!

FYI, our Kickstarter funded and we launched our Itch page where anyone can purchase a digital copy of Inky and the Alien Aquarium!
https://pocket-pulp.itch.io/inky-and-the-alien-aquarium
We plan on doing one more small run of carts in a couple months, join our mailing list to be notified when that happens (https://pulp.biz).
Our Kickstarter launched today!
We're very excited!
We've been busy printing off the boxes and manuals, and released the trailer a couple days ago... the Kickstarter should launch in the next month or so... it always feels like it's right around the corner, then we realize we need to do something else.
On the plus side, if you choose to participate in the Kickstarter, we will be able to fulfill it very quickly, because all the leg work is done!
Here's the trailer:
We just released our free demo! Sign up here and get it emailed to you:

I'm really curious what people think :)

What do you mean by virtual console? Certainly not this definition right?
Things like PICO-8, TIC-80 -- oops, I should have said fantasy console.
I am excited and hopeful for Pocket Pulp's success. Is your partner on this forum?
No, she's pretty shy online for some reason, lol.
...whelp I just climbed out of your van-dwelling rabbit hole. Your transparency and vulnerability on display is impressive. I've gone on a few road trips living out of Jeeps, so a lot of that resonates with me.
Yes living in a van was a blast! I'm glad you enjoyed my blog on it!
We saved up money and took this past year off, which allowed us to work on our business full time. Unfortunately we have to go back to work to pay the bills, but it's been a lot of fun this past year.
I work professionally as a web developer, and my partner works in marketing.
Working on a game on nights and weekends is really tough, I've tried that over the years, and never really had success with it... but everyone is different. For me, it's better to save up and take time off between jobs (and keep expenses low, so money lasts longer!).
My favorites are Tony Hawk Pro Skater 2, and Wario Ware.
I was always impressed with the 3D characters in the Tony Hawk series. The levels were a lot of fun to explore and find secrets in too.
Wario Ware is just silly and I love it. The stories are ridiculous and the minigames are fun.
