Reading and Playing DLsite Downloads: File Formats, the Spec Table and System Requirements (Checked Nov 10, 2026)

* This page introduces adult (18+) content. If you are under 18, please do not view or purchase. Age verification required.

A word from the Researcher. Every DLsite product page carries the same small table of specs, and it answers almost every practical question a buyer has — what kind of work this is, what file you will actually receive, which languages it runs in, and how much disk it wants. The lab reads that table before it writes a single word about a work. This page teaches the same reading, field by field, with the real values taken from listings checked on November 10, 2026.

Nothing here is guesswork: each field name and each format value below appears, in those words, in the spec table or description of live DLsite product pages. The three listings at the end are the worked examples — one per shelf.

01 The spec table, field by field

Open any product page and find the table with these rows. They are the same on every shelf:

Field	What it tells you
Product format	What the work is. On manga it reads simply "Manga"; on voice works, "Voice / ASMR". On games it does not say "Game" — it names the game's kind instead: Role-playing, Adventure, Simulation, Action, sometimes with Voice, Music or Animation appended. A game-looking title whose Product format reads "Manga" is a manga; this row outranks the cover art. (It is the row this whole wing is fact-checked against.)
File format	What you will actually download — decoded shelf by shelf in section 02.
Supported languages	The languages the work itself runs in, listed in words. If English is not in this row, the work is not in English, whatever the storefront language is set to. This row — together with the [ENG Ver.] and [ENG Sub] prefixes explained in the tags guide — is the translation check.
Genre	The tag row. Each tag is a filter link; the genre glossary translates the important ones.
File size	The download's weight, from a voice work's few hundred megabytes to several gigabytes for 3D games. Check it against your connection and disk before, not after.
Release date / Age	When the work went on sale, and its age rating — the adult shelves read "R18".

02 File format, shelf by shelf

Manga and CG: image and PDF deliveries. A manga listing's File format names the containers inside the download — the worked example below reads "JPEG PDF file", meaning the pages arrive as JPEG images and as a PDF. Image files open in any comic or image viewer; the PDF opens anywhere. There is no special DLsite software between you and the pages once the files are down.

Voice and ASMR: WAV and MP3. Voice listings name audio formats — "WAV / MP3" is the common pairing, and some listings spell out that both are bundled. WAV is the uncompressed master: the full recording, at full size. MP3 is the compressed copy of the same tracks: smaller, and the one that goes on a phone. When both are listed, you choose per device — archive the WAV, carry the MP3. Binaural works are meant for headphones either way; the format row, not the player, is what changes.

Games: Application — and watch for the APK note. A game listing's File format reads "Application": a program you download, unpack and run, not a document or a media file. Some listings add a second line to that value — "Application APK Included" — which means an Android APK ships in the same download beside the PC program. If a listing says only "Application", do not assume a phone version exists; the spec table is where that promise would be written.

03 System requirements: they live in the description

The spec table has no operating-system row. When a circle states requirements for a game, they are written in the work's description, under a heading that reads "Product Information / System Requirements", as plain lines — CPU, Memory, Video. One of this wing's own picks, Karryn's Prison, states them exactly that way: a 2.5+ GHz processor minimum (3+ GHz recommended), 8 GB of RAM minimum (16 GB recommended), and a DirectX 9 / OpenGL 4.1 capable GPU. The reading rule: if the description carries that heading, those lines are the requirements; if it does not, the circle has not published any, and the File size row is your only hardware-adjacent fact.

04 After the purchase: downloads and My Items

Bought works are delivered as downloads from your library, and the files are yours to keep and re-download. DLsite also runs its own viewer side: the "My Items" entry in the site's navigation (it appears when you are logged in) leads to DLsite Play at play.dlsite.com, where your purchased works are gathered under your account. The plain reading: download for your own archive and players, or open My Items when you want the store itself to hold the shelf. Which route suits a given work starts, as always, with its File format row.

05 The three formats, as three real listings

[ENG Ver.] Cuckoo Wife Mayumi ~Voluptuous, Lust-Filled Flesh-on-Flesh Sex~: ¥275 (50% OFF; list ¥550)

The manga shape: Product format "Manga", File format "JPEG PDF file" — pages as images and as a PDF, readable in anything. Its genre row doubles as a glossary exercise: Married Woman, Cuckoldry (Netorare) and Pregnancy / Impregnation, all translated on the glossary page.

Format: Manga. File format: JPEG PDF file. Listed as [ENG Ver.]. Price checked Nov 10, 2026: ¥275 (50% OFF; list price ¥550).

[ENG Sub] Your Chill, Unemployed Big Sis Lets You Use Her Sexy Body at a Summer Resort: ¥1,320 (20% OFF; list ¥1,650)

The voice shape: Product format "Voice / ASMR", File format listing WAV and MP3 bundled together — the master recording and the portable copy in one purchase, which is why this listing anchors the audio section above. The work itself opens the lab's onee-san ASMR shelf.

Format: Voice / ASMR. File format: WAV / MP3. Listed as [ENG Sub]. Price checked Nov 10, 2026: ¥1,320 (20% OFF; list price ¥1,650).

The game shape: Product format "Role-playing" (with Voice and Music), File format "Application", File size 1.37 GB — and the description carrying the "Product Information / System Requirements" block quoted in section 03. Everything this page teaches is on this one listing.

Format: Role-playing Voice Music (DLsite work type: RPG). File format: Application. English listed in Supported languages. Price checked Nov 10, 2026: ¥2,640 (20% OFF; list price ¥3,300).
