MAME
Emscripten Javascript and HTML will help to run this emulator within a web application
Depends
To compile MAME, you need a C++14 compiler and runtime library. We support building with GCC version 7.2 or later and clang version 5 or later. MAME should run with GNU libstdc++ version 5.1 or later. - MAME All Platform Docs
GCC 7.2 or later
gcc -v
Using built-in specs.

Installation
git clone https://github.com/mamedev/mame
cd mame && make
If you have access to multiple cores, be sure to pass the -j5 flag in the command above to take advantage of the extra processing power. Generally, the rule of thumb is to pass the number of cores in your processor + 1 to the -j flag.
Emscripten
Depends
Python, CMake, and Java are not provided by emsdk. The user is expected to install these beforehand with the system package manager - Emscripten Linux Install Docs
# Install Python
sudo apt-get install python2.7
# Install CMake (optional, only needed for tests and building Binaryen)
sudo apt-get install cmake
# Install Java (optional, only needed for Closure Compiler minification)
sudo apt-get install default-jre
Installation
This is very well documentated at EMscripten.org
# Get the emsdk repo
git clone https://github.com/emscripten-core/emsdk.git
# Enter that directory
cd emsdk
# Fetch the latest version of the emsdk (not needed the first time you clone)
git pull
# Download and install the latest SDK tools.
./emsdk install latest
# Make the "latest" SDK "active" for the current user. (writes .emscripten file)
./emsdk activate latest
# Activate PATH and other environment variables in the current terminal
source ./emsdk_env.sh
Errors
Had this issue as well at a few different points during installation, running Kubuntu 20.04 in a virtualbox VM. I was able to manually wget the files returning 104's with no problems, though. After reading the previous comment, I just kept rerunning the command to install and eventually each error resolved itself. Errors I encountered are below
First 104

Usage
As a test, from within the root directory of our mame installation, run the following command to compile pacman.cpp
emmake make SUBTARGET=pacmantest SOURCES=src/mame/drivers/pacman.cpp
If you have access to multiple cores, be sure to pass the -j5 flag in the command above to take advantage of the extra processing power. Generally, the rule of thumb is to pass the number of cores in your processor + 1 to the -j flag.
Errors
I faced the following error with LzmaEnc.c
../../../../../3rdparty/lzma/C/LzmaEnc.c:1405:9: error: misleading indentation; statement is not part of the previous 'if' [-Werror,-Wmisleading-indentation]
{
^
../../../../../3rdparty/lzma/C/LzmaEnc.c:1401:7: note: previous statement is here
if (repIndex == 0)
This can be resolved by opening the file referenced in the error above for editing within vim. Once open, run :1405 to jump to the block of code resulting in errors. You should see the code block below
1404 /* if (_maxMode) */
1405 {
1406 UInt32 lenTest2 = lenTest + 1;
1407 UInt32 limit = lenTest2 + p->numFastBytes;
1408 if (limit > numAvailFull)
1409 limit = numAvailFull;
1410 for (; lenTest2 < limit && data[lenTest2] == data2[lenTest2]; lenTest2++);
1411 lenTest2 -= lenTest + 1;
1412 if (lenTest2 >= 2)
1413 {
1414 UInt32 nextRepMatchPrice;
1415 UInt32 state2 = kRepNextStates[state];
1416 UInt32 posStateNext = (position + lenTest) & p->pbMask;
1417 UInt32 curAndLenCharPrice =
1418 price + p->repLenEnc.prices[posState][lenTest - 2] +
1419 GET_PRICE_0(p->isMatch[state2][posStateNext]) +
1420 LitEnc_GetPriceMatched(LIT_PROBS(position + lenTest, data[lenTest - 1]),
1421 data[lenTest], data2[lenTest], p->ProbPrices);
1422 state2 = kLiteralNextStates[state2];
1423 posStateNext = (position + lenTest + 1) & p->pbMask;
1424 nextRepMatchPrice = curAndLenCharPrice +
1425 GET_PRICE_1(p->isMatch[state2][posStateNext]) +
1426 GET_PRICE_1(p->isRep[state2]);
1427
1428 /* for (; lenTest2 >= 2; lenTest2--) */
1429 {
1430 UInt32 curAndLenPrice;
1431 COptimal *opt;
1432 UInt32 offset = cur + lenTest + 1 + lenTest2;
1433 while (lenEnd < offset)
1434 p->opt[++lenEnd].price = kInfinityPrice;
1435 curAndLenPrice = nextRepMatchPrice + GetRepPrice(p, 0, lenTest2, state2, posStateNext);
1436 opt = &p->opt[offset];
1437 if (curAndLenPrice < opt->price)
1438 {
1439 opt->price = curAndLenPrice;
1440 opt->posPrev = cur + lenTest + 1;
1441 opt->backPrev = 0;
1442 opt->prev1IsChar = True;
1443 opt->prev2 = True;
1444 opt->posPrev2 = cur;
1445 opt->backPrev2 = repIndex;
1446 }
1447 }
1448 }
1449 }
Notice the commented out /* if (_maxMode) */ on line 1404, right above the block causing errors.
In the interest of using vim efficiently, this can be fixed in a few keystrokes from our current position after running :1405 within vim. Simply press v%<< to correct this block and save with :w. Now retry
Retry the compilation of pacmantest using the same command as before and everything should complete normally.
