Disc swapping

What are games that make use of opening the disc tray and putting another disc in while the game runs?

Monster Rancher is the clear candidate, with the ability to summon monsters from CDs (though did that survive past the ps1 games in any form?).

There is some smattering of other games that support swapping in CDs to play music while still playing the game (or some portion of it) out of memory. Baby Universe is one example of doing this.

What are other games that do things like this? Was this only done on Playstation? What’s the weird pc engine version of this? (And yeah not just asking for multi-disc games)

One interesting use-case is append discs, or at least that’s how Konami called them. These are commercial “data discs” released after a game’s original release, that required booting the original disc first in order to then access the additional contents on the new discs. DLCs before the DL was possible, in other words.

I would hazard to guess the best known case in the West is the original **Persona 3 Fes**, which had both a standalone and an _Append Disc_ version in Japan.

As I mentioned above, I am pretty sure Konami either coined the term or made it standard in the Japanese games industry, notably with the various **Bemani** series ported to PS1 and later platforms.

I won’t go _The Complete History of Append Discs_ on y’all but just another fun case I want to mention is that the PSP got them as well. Here’s the Append (Universal Media) Disc version of **God Eater Burst**.

Chaz this is neat stuff that I didn't know much about but also not really what the question asks!

They're talking about games that ask you to put a music cd or similar in as game content.

For ps1 there's Vin Ribbon of course. That took your music tracks and turned them into rhythm game playfields.

For PC Engine, there absolutely is one of these but I don't remember what it's called! I can envision the cover! It's got a chibi warrior on it! Aaaah

[update:] it's CD Battle Heroes of Light: https://pcengine.co.uk/HTML_Games/CD_Battle-Heroes_of_Light.htm

My Append Discs fit the criteria!

@“◉◉maru”#p142682 I had no idea that was a way things like FES were released!

Here's one I just learned about today

For some reason the PAL versions of Grand Theft Auto: London 1969 and Metal Gear Solid: Special Missions were sold as PC-style ‘expansion packs’ and required you to swap in the original games and then back again in order to start playing, despite them not actually requiring any data from those original discs. You could even skip the disc swap entirely with an Action Replay (or similar), launching the main executable directly.

_Edit:_ Googled it. One reason I’ve seen given for this is that the expansion disc needs to “download the language data” from the original disc in order to dynamically choose a language based on the specific PAL region of the original game. If this process fails (like when launching the executable directly), it defaults to English. This is silly. The same could easily have been achieved with a language select screen like many other PAL games had.

It did! Monster Rancher 3, 4, and EVO on the PS2 still did CDs (and DVDs!). I think the switch to non-CD generation happened with Monster Rancher Advance.

The DS games would let you generate monsters with GBA cartridges, which is kinda cool and almost this.

All I could think of when I saw this thread subject is the early days Playstation disc swap method, used to both play imports and to skirt the system's copy protection for playing bootleg or burned discs. I‘m pretty sure I recall games eventually rolling out where the method couldn’t be used anymore (and even when I bought my first gen PS1, the ones being sold by then allegedly couldn't do the swap method), and the whole thing always felt really precarious– I initially had a bodge that used a paperclip, and eventually I bought a fancy spring sold explicitly to be used to do the swap.

I feel like this is in the spirit of this thread? Even though it's not adding content to one game from another.

In similar fashion you can get I think one crappy item by playing Final Fantasy Tactics A2 for DS with FFTA for GBA in the cart slot.

Might not fully be in the spirit of the thread (and I've mentioned it elsewhere on the forum), but Ridge Racer on PSX lets you put a music cd in after the game loads. Listen to your own tunes instead of the rad Ridge Racer joints for some reason? This is more of a side-effect of the entire game being loaded into the system memory than a feature though.

Now this is what I’m talkin bout - simple series racing game with a monster-rancher style track editor: https://www.youtube.com/watch?v=I_AvXhUCECU

The Vigilante 8 series on PlayStation for a few reasons.

Both games allowed you to swap out with a music cd after a game had started so you could listen to your own tracks.

The 2nd game allowed you to play the original games levels with a secret disc swap method. The Dreamcast version allowed you to do this without the disc by entering a code on the VMU.

This one is more of a bug, while playing ps1 Lunar silver star story bonus disc video, swapping in Xenogears discs would play all of the Xenogears FMVs. 2nd disc has a vocal song video that’s not accessible while playing the game.

Dezaemon Kids is wild! (A PSX shooting game maker if you’re not familiar)

In the BGM setup options for your custom game, you can’t make your own music, but you can assign things like “Stage 1 boss song” to either one of the many sample songs, OR to “Track x of the currently inserted CD”.

I’ll have to mess with it more to see when it cues you to open the tray during play if you do this, cuz it seems like you can have a mix of sample songs or CD songs among your settings. It would be hilariously disruptive to need to switch right when getting to the encounter.

I think it’s a pretty frickin cool capacity to have this, cuz stage editing has timestamps n whatnot, so the potential for neat audio-gameplay synergies is quite high. Bless em!
