The SummerCart64: My Whole N64 Shelf, on the Sofa

The collection has grown into something I am quietly proud of, and these days it lives on a shelf where I can look at it. That is a deliberate choice. As I have got older, space has stopped being free. The things I want in the living room have to earn their place, and a stack of cartridges I swap in and out one at a time was slowly losing that argument. I still love the boxes and the spines and the sense of a collection you can see. I just did not love hunting for a specific cart behind everything else every time I wanted to play.

I already knew the fix, because I had just done it for the Game Boy. A flash cart had turned my whole GBA shelf into one SD card, and it had been such an easy, obvious pleasure that the only real question was why I had waited. So the plan for the N64 was simple. Give it the same treatment. Keep the collection on the shelf as the thing I look at, and keep one cart in the console as the thing I play.

What it actually is

The SummerCart64 is an open source flash cart for the N64. That is worth saying plainly, because it changes how you get one. The whole project is out in the open, so you can build your own if you have the skills and the patience, or you can buy one already made. I went the buying route, caught one in a sale, and I have no complaints about that decision at all.

I put a decent SD card in it, loaded up everything I actually want to play, and that was more or less that. It does exactly what it says on the tin. It boots on the real console, it loads games, it writes saves without any drama. There is no launcher weirdness to fight, no ritual to remember. Cart in, console on, pick a game, play. My whole collection, in the living room, on one card. That was the entire goal and it hit it on the first evening.

There is one honest blemish, and I would rather mention it than pretend. On my unit the USB-C port never showed up as a device on my computer. From what I can tell that tends to be the connector itself rather than the board, and it is a known soft spot on the cheaper builds. It sounds worse than it is. I load the card by pulling the SD out and putting files on it the normal way, which is exactly how I expected to do it anyway, so in practice it has never once got in the way. If you plan to lean on the USB features it is worth knowing about. For how I use the thing, it is a footnote.

The part I actually wanted

Here is the thing I did not expect to care about as much as I do. The real treat was not the convenience of the shelf on a card. It was ROM hacks, running on the actual console, on the actual sofa.

I have never once bothered to emulate a hack on my computer. I know I could. I just do not want to. If I am going to play an N64 game I want to be sat where I play N64 games, with the real controller in my hands and the real hardware doing the work. Being able to try the fan favourites everyone has been talking about for years, on the machine they were meant for, is genuinely brilliant. It is the whole reason I care about this hobby, made real. No emulator, no compromise, just the game on the box under the telly.

Getting a hack ready does take a little groundwork, and it is worth being honest that there is a small learning curve. The short version, and this all assumes you are working from a copy you dumped from your own cartridge:

First, your ROM needs to be in the right format. The N64 has a couple of byte orderings floating around, and the one you want is .z64, the native big-endian format. If yours is a .n64 file it is just byte-swapped, and a swapper tool will flip it for you in a second. I used this one.

Then you patch it. A ROM hack is distributed as a patch, not as a game, which is exactly as it should be, because the patch is the creative work and the ROM is the part you already own. I got my patches from RomHacking.net and applied them with their browser-based patcher, which handles the common formats you will run into. That patched file is what goes on the card.

None of that is hard once you have done it once. It is just a couple of steps that nobody tells you about up front.

The black screen, and the loft

And then, of course, I hit a wall. Some hacks booted straight to a black screen. Games that, as far as I could tell, had no business needing anything special. I was wrong about that. They needed the Expansion Pak.

If you have not run into this before: the N64 shipped with a Jumper Pak in the memory slot, and the Expansion Pak is the 4MB upgrade that replaces it. A fair few games and a good number of hacks genuinely require it, and when it is missing you get exactly that, a black screen on boot and no explanation. So the cart was fine. The console was fine. I was just missing a small grey brick.

Which is where the loft comes back in. The console downstairs had the Jumper Pak. The Expansion Pak was in the other N64. The forgotten one. The bundle I barely remember buying. Naturally it was at the furthest possible point in the loft, at the bottom of a stack, behind everything else, as if it had been placed there specifically to test how much I wanted this. I did want it. I dug it out. And that impulse purchase I could not even explain to myself years ago turned out to be the exact part I needed. There is more to that second console's story, but it can wait for its own day.
