Play all your childhood games in the highest possible quality. My consoles function better than they did when they were manufactured! I, Leah Rowe, am deeply passionate about retro games and I want to bring you the best possible quality. See below for more specific technical information.

This is the classic 16-bit Sega MegaDrive videogame system (known as Sega Genesis in the US), refurbished to full operational order (and fully cleaned). Additionally, certain fixes/tweaks have been made so as to optimize it for maximum possible picture/sound quality on a modern HDTV (It is not HD. This will still work on an old CRT TV, the ones that weigh a ton. However, it is optimized for the upscaler on modern HDTVs). No more manual tuning in to get a good picture (SCART cable is provided)! You will see vivid pixels, in full colour, that are sharp and not blurry.

Enhancements have been made, such as the ability to play American/European/Japanese games region-free with perfect compatibility. An overclock switch is installed, for games like Sonic that have slowdowns. - Voultar's RGB bypass board is installed, for best possible jailbar-free picture quality. FireBrandX's M1 Mini Mega is installed, for best possible audio quality.

Full documentation is provided with all orders, with simple instructions so that you can go in-game immediately! Additionally, a full 2-year warranty is provided.

Power adapter, RGB SCART cable (for the TV) and joypad included (3 button joypad). 2nd joypad available for 30 GBP +UKVAT

Price per unit: 118 GBP (plus 20% British VAT if shipping to UK or EU). Shipping worlwide, exporting from the UK. Email your name/address and I will send you an invoice. Payment accepted via wire transfer (BACS, ACH, SEPA, SWIFT, etc.)

Shipping: 15 GBP for UK. 35 GBP for EU. 60 GBP for the rest of the world.

NOTE: as of 11 December 2019 my emails are a mess (from my other company). If you wish me to respond quickly, DM me on my twitter: - I will give you payment instructions and attach an invoice. Tell me your name, address and email.

Alternatively, pay 150 GBP and send your unmodified console to me. I will do the same mods. I will provide you with a suitable shipping address. This is an all inclusive service where I totally pimp out your MegaDrive or Genesis console.

Technical specifications

All electrolytic capacitors are fully replaced. This extends the lifetime of the system; I estimate up to 10 years at least. A 2 year warranty is provided on all orders.

Boot games region-free! Cartridge slot widened to fit Japanese cartridges. 53.69mhz crystal installed for correct NTSC timings. Voultar RGB bypass and Firebrandk M1 Mini Mega installed (replaces the default video/audio amps, causing the best possible video/audio quality). Japanese/English language switches installed. M1 Mini Mega line-level stereo output goes to front headphone jack, bypassing the volume control (constant headphone-level audio volume is outputted, also suitable for speakers). 10MHz crystal provided, to overclock the CPU (an enable/disable switch is installed).

Switches provided are as follows (also see pic):

In my opinion, the MegaDrive 2 is superior overall to the Megadrive 1 since it’s smaller and uses less power. HOWEVER, the various chips like the m68k, PSG, Z80 and whatnot are combined into a single Genesis on a Chip (GOAC), which is not as accurate. If you value perfect accuracy, I strongly recommend purchasing the MegaDrive model 1 seen here. I’m all about accuracy, so my personal MegaDrive is a VA0 model 1 :)

WARNING1: Installing the RGB Bypass board removes the Composite Video output

WARNING2: Included power adapter is for 240V wall sockets (e.g. European and many asian countries). For 110V countries like USA/Japan/Canada etc, you can purchase a replacement power adapter online. I recommend only the official Sega power adapter. Make sure to buy a Genesis 2 one, not a Genesis 1 power adapter!

The RGB Bypass board removes the majority of jailbars on the screen, which means that the picture quality will be extremely sharp on modern HDTVs or upscalers.
