This is achieved in the classical buffer overflow exploitation by estimating the offset of the return address on the stack. Once the exploit is loaded into RAM after RLE decoding, it is necessary to trigger payload execution from the load address.

Fortuna Rev1 hung on black screen when whole icons were loaded due to scarce room in RAM, this was fixed in Fortuna Rev2.Įxploit is loaded into RAM when MC contents are shown along with the distinctive Fortuna “white icon”, which actually is NOP-Sled. NOP-Sled is used in this case to create room for remaining game saves in MC. Hence, for Fortuna v1, the load address is 0x20b020b0 and for Fortuna v2, the load address is 0x20c020c0.

This is because of the way the RLE decoder repeats load address by using halfwords. The NOP-Sled technique is used in both versions, whose size is chosen to have a load address for payload (shellcode) of the form: 0x20XX20XX. Exploitation is performed by using the following approach: NOP-sled + shellcode + return address repetition + zero pad. RLE decoder in OSDSYS has no boundary check at all. First, Fortuna is based on the exploitation of a buffer overflow vulnerability in OSDSYS. They are similar but have slight differences related to the payload and its load address. įortuna v1 and Fortuna v2 were both reverse engineered. CTurt’s FreeDVDBoot helped me out to polish the exploit implementation as well. His post was the starting point of what I’m about to describe here. The conjectures from were very useful, and they gave some insights however, was the first person that first described some technical details about Fortuna and how it works. Still, in the end, he decided to maintain this exploit in secrecy due to several reasons I'm not going to describe here.įortuna’s magic and the secrecy around it made me very curious, so I started reading posts from krat0s, CTurt, and in order to get some clues to reverse engineer Fortuna. At first, krat0s was willing to prepare a technical write-up about Fortuna’s internals. The vulnerability Fortuna is based on was described first by some years ago, and developer krat0s exploited it around a year ago. As an additional advantage, Fortuna does not require MagicGate Memory Cards (MCs).

Only one specific FAT console model: SCPH-500XX with BIOS v1.90įortuna is the newest MC-based exploit for PS2 consoles, allowing homebrew software to run on consoles with BIOS v2.30, which are incompatible with FreeMCBoot.OpenTuna is now compatible with each PS2 Console starting from SCPH-18000 up to SCPH-90010 and PS2 TV.

Since it is open source, it will allow porting it to other hardware versions, including TEST consoles.

Thanks to added fat compatibility, some test models can use OpenTuna as MC-based exploit.

It allows embedding compressed and uncompressed executables to the exploit icon.

Also, we included OPL on the release package, so you are ready to play once you install it.Now installation can be performed on either slot1 or slot2 for each compatible model. We included an easy to use installer were you only need to press X to install it. It is made to be easy to use by the user.While Fortuna was merely a proof of concept, OpenTuna was made having future development in mind:.Protokernels (SCPH-10000 and SCPH-15000) are excluded and OpenTuna won't be ported to them (at least by me), I'm not sure if they're hackable or not. Yeah, it turned out almost all PS2 consoles are hackable this way, as additional advantage OpenTuna does not require MagicGate compliant MCs.

Good news!!, OpenTuna is now compatible with each PS2 Console starting from SCPH-18000 up to SCPH-90010 and PS2 TV (ROM versions ranging from 1.10 to 2.30).

OpenTuna is an open source version of 'Fortuna', based on reverse engineering!!!.
