 # shadPS4
 
 An early PS4 emulator for Windows and Linux written in C++
-
+by shadow , skmp , wheremyfoodat
 
 [Check us on twitter](https://twitter.com/shadps4 "Check us on twitter")
 
 # Status
 
-Currently, it can only load PS4 ELF files.
-
-Progress is focused on videoout_basic.elf from SDK demos, currently, it can load with fully working graphics. Others probably won't run since they might not be able to relocate all necessary functions
+Early progress , a small amount of ps4 sdk demos and homebrew games working

+v0.0.2 21/10/2023
+=================
+-using cstdint header in variable types
+-run_main_entry: Rewrite in asm for stack setup
+-printf libc implementation for work with sysv_abi
+-initial pad emulation (only digital pad atm)
+-Implemented sceVideoOutIsFlipPending 
+-Added auto stubs , now unsupported hle function will resolve as empty stubs
+-Rewrote libc_cxa functions
+-Libc implementations ( _ZdlPv,_Znwm,rand,_Fsin,qsort,free,strncpy,memmove,atan2f,pow,_Sin)
+-ET_SCE_DYNAMIC behaves as valid for execution now.
+-Initial FileSystem work (not yet usable).

+# Result
+This is an adaption of [https://github.com/oktal/result](https://github.com/oktal/result). Make sure to support the original library!
+
+## Overview
+
+`Result<T, E>` is a template type that can be used to return and propage errors. It can be used to replace
+exceptions in context where they are not allowed or too slow to be used. `Result<T, E>` is an algebraic data
+type of `Ok(T)` that represents success and `Err(E)` representing an error.
+
+Design of this class has been mainly inspired by Rust's [std::result](https://doc.rust-lang.org/std/result/)
+
+```
+
+struct Request {
+};
+
+struct Error {
+
+    enum class Kind {
+        Timeout,
+        Invalid,
+        TooLong
+    }
+
+    Error(Kind kind, std::string text);
+
+    Kind kind;
+    std::string text;
+};
+
+Result<Request, Error> parseRequest(const std::string& payload) {
+    if (payload.size() > 512) return Err(Error(Kind::TooLong, "Request exceeded maximum allowed size (512 bytes)"));
+
+    Request request;
+    return Ok(request);
+}
+
+std::string payload = receivePayload();
+auto request = parseRequest(payload).expect("Failed to parse request");
+```
+
+To return a successfull `Result`, use the `Ok()` function. To return an error one, use the `Err()` function.
+
+## Extract and unwrap
+
+To extract the value from a `Result<T, E>` type, you can use the `expect()` function that will yield the value
+of an `Ok(T)` or terminate the program with an error message passed as a parameter.
+
+```
+Result<uint32_t, uint32_t> r1 = Ok(3u);
+
+auto val = r1.expect("Failed to retrieve the value");
+assert(val == 3);
+```
+
+`unwrap()` can also be used to extract the value of a `Result`, yielding the value of an `Ok(T)` value or terminating
+the program otherwise:
+
+```
+Result<uint32_t, uint32_t> r1 = Ok(3u);
+
+auto val = r1.unwrap();
+assert(val == 3);
+```
+
+Instead a terminating the program, `unwrapOr` can be used to return a default value for an `Err(E)` Result:
+
+```
+Result<uint32_t, uint32_t> r1 = Err(9u);
+
+auto val = r1.unwrapOr(0);
+assert(val == 0);
+```
+
+## Map and bind
+
+To transform (or map) a `Result<T, E>` to a `Result<U, E>`, `Result` provides a `map` member function.
+`map` will apply a function to a contained `Ok(T)` value and will return the result of the transformation,
+and will leave an `Err(E)` untouched:
+
+```
+std::string stringify(int val) { return std::to_string(val); }
+
+Result<uint32_t, uint32_t> r1 = Ok(2u);
+auto r2 = r1.map(stringify); // Maps a Result<uint32_t, uint32_t> to Result<std::string, uint32_t>
+
+assert(r2.unwrap(), "2");
+```
+
+Note that `map` should return a simple value and not a `Result<U, E>`. A function returning nothing (`void`)
+applied to a `Result<T, E>` will yield a `Result<void, E>`.
+
+To map a function to a contained `Err(E)` value, use the `mapError` function.
+
+To *bind* a `Result<T, E>` to a `Result<U, E>`, you can use the `andThen` member function:
+
+```
+Result<uint32_t, uint32_t> square(uint32_t val) { return Ok(val * val); }
+
+Result<uint32_t, uint32_t> r1 = Ok(3u);
+auto r2 = r1.andThen(square);
+
+assert(r2.unwrap(), 9);
+```
+
+Use `orElse` to apply a function to a contained `Err(E)` value:
+
+```
+Result<uint32_t, uint32_t> identity(uint32_t val) { return Ok(val); }
+
+Result<uint32_t, uint32_t> r1 = Err(3u);
+assert(r1.andThen(identity).orElse(square).unwrap(), 9);
+```
+
+## The TRY macro
+
+Like Rust, a `TRY` macro is also provided that comes in handy when writing code that calls a lot of functions returning a `Result`.
+
+the `TRY` macro will simply call its argument and short-cirtcuit the function returning an `Err(E)` if the operation returned an error `Result`:
+
+```
+Result<void, IoError> copy(int srcFd, const char* dstFile) {
+
+    auto fd = TRY(open(dstFile));
+    auto data = TRY(read(srcFd));
+    TRY(write(fd, data));
+
+    return Ok();
+}
+```
+
+Note that this macro uses a special extension called *compound statement* only supported by gcc and clang
