It had a Philips SCC68070 CPU at 15.5 MHz with 1MB of RAM. Notably, it featured intellectual properties from Nintendo, such as Mario and Zelda, due to previously having tried to develop a CD add-on for the measure in which how many pixels are displayed [[Super Nintendo emulators|SNES]]. Their takes on Nintendo intellectual property were so infamously terrible that you would be hard-pressed to find anyone who doesn't think of them when you mention the CD-i. However, there were a few cult classic games for the screensystem.

For emulation of 2D systems, the resolution can only be upscaled, making the pixels more apparent. For emulation of 5th generation consoles and newer, the internal resolution can be increased to make the game look sharper.__TOC__ ==Console ResolutionsEmulators=={| class="wikitable"|style="text-align:center;"! scope="col"|SystemName! scope="col"|Native Resolution|-|[[Atari 2600 emulators|Atari 2600]]|160×192*|-|[[Nintendo Entertainment System emulators|NES]]|256×224 Platform(NTSC), 256×240 (PALs)! scope="col"|-Latest Version! scope="col"|[[Master System emulators|Sega Master System]]|256×192, 256×224, 256x240 <abbr title="Digital Video Cartridge">DVC</abbr><ref group=N>Emulation of the Gate Array MPEG Digital Video Cartridge (some PAL DVC) is required for certain games)|-|[[Super Nintendo emulators|SNES]]|256×224, 512×448 (NTSC), 256×240, 512×480 to be playable (PAL)|-|check [[Virtual Boy emulators|Virtual Boy]]|384×224 (per screen)|https://github.com/mamedev/mame/blob/master/hash/cdi.xml MAME's CD-|[[Sega Genesis emulators|Sega Genesisi hash list]]|320×224, 256×224, 320x240 (some PAL gamesfor mentions of "DVC")|-|[[Game Boy.</Game Boy Color emulators|Game Boy/Color]], [[Master System emulators|Sega Game Gear]]|160×144|-ref>! scope="col"|[[Nintendo 64 emulatorslibretro|Nintendo 64Libretro Core]]|640×240, 640×480**|-! scope="col"|[[PlayStation emulatorsEmulation Accuracy|PlayStationAccuracy]]! scope="col"|256×224p, 256x240p, 320x224p, 320×240p, 512x224p, 512×240p, 640x224p, 640x240p320x448i, 320x480i, 370x448i, 370x480i, 512x448i, 512x480i, 640x448i, 640×480i|<abbr title="Free/Libre and Open-Source Software">FLOSS</abbr>! scope="col"|[[WonderSwan emulators|WonderSwan]]|224×144|-Active! scope="col"|[[Game Boy Advance emulatorsRecommended Emulators|Game Boy AdvanceRecommended]]|240×160|-|[[Pokémon mini emulators|Pokémon Mini]]|96×64

===Comparisons===;[[MAME]]:Has a driver for the CD-i but support is incomplete, as it still doesn't emulate the Digital Video Cartridge as of July 2021.<nowikiref>*https://github.com/mamedev/mame/issues/1170</nowikiref>Starting the game from disc is recommended; this can be done with the built-in frontend by picking the specific game or through a soft reset after mounting the disc. This is a rough figure given also the only CD-i emulation currently available in [[libretro]] (using the MAME cores), which means that (for simplicitynow) it's sakethe easiest and the most stable method of emulating the CD-i. Compared to CD-i Emulator 0.5. In reality3 beta 4, the Atari 2600 doesnMAME is easier to control and its audio emulation is better in some cases.;TinyCDi:An unofficial build of [[MESS]] from 2009 made by one of MAME't really output pixelss active developers, and Haze. This build is named such that it has no limits only focuses on the number of lines it can displayCD-i. HoweverIt uses a fixed game list, but it did have a hard limit on works better than the number of horizontal color clocks official MAME builds, especially with games like Zelda's Adventure for drawing example. On the picture (160)other hand, and most some games only output 192 lines, hence have more issues than they have on the commonly given resolution of 160x192official MAME build.;CD-i Emulator:A closed-source payware emulator. The latest public release, 0.5.3 beta 4, dates all the way back from 2018 and is unfortunately now ''unplayable'' without a crack, due to the way that licenses are handled (or not) in the beta releases. The beta does have proof-of-concept emulation of the Digital Video Cartridge but compatibility may still be an issue<nowikiref>**http://www.cdiemu.org/site/relnotes.htm</nowikiref>While N64 games ran at various resolutions internally. Despite the long time between releases, this emulator is still in practice seemingly active development as of October 2020, with work being done on the hardware's VI component always doubled next version (likely called 0.6) that reportedly supports most of the scale horizontally, DVC games and output in either 640x240p or 640x480i, though there is letterboxing at timesalso has several other improvements<ref>https://cdii.blogspot. com/search/label/CD-i%20Emulator<nowiki/ref>***</nowikiref>Similar to N64, games ran at various resolutions internally[https://tcrfwww.nettheworldofcdi.com/Help:Contentscd-i-emulation/cd-i-emulator-053beta5-titles-compatibilities/Taking_Screenshots#GameCube</Wii]ref>.;CD-iCE:One of the earliest CD-i emulators. It doesn't need a BIOS, though output but it was only developed to be able to play Rise of the Robots (no other game is usually in 240psupported).

==References==<nowiki>****<references /nowiki>This is the "true" resolution of the top screen and what games will be rendered at in full 3d mode, however, due to said 3d effect the horizontal resolution is effectively halved. Each eye will only see 400x240 and games run in 2d mode will (normally) be rendered at 400x240 [https://en.wikipedia.org/wiki/Nintendo_3DS#Hardware]

==Integer Scaling=={{Main|Scaling}}Upscaling the resolution will only look good if you scale it by integers (2x, 3x, 4x, etc.). If you are scaling with non-integers, you can make the image look better using the [[Shaders_and_Filters#Pixellate|PixellateCategory:Consoles]] shader.[[Category:FAQsFourth-generation video game consoles]]
